SSL certificates - sec_error_unknown_issuer

Difficulty already in your browser. Get these SSL errors on all other sites starting to get really annoying! There is nothing wrong with SSL certificates or sites. It's your browser that is unable to verify certificates.

Quote: the browser should come with all certification authorities

Note that Mozilla has a strong policy to decide that the CA registration certificates root.

The required intermediate certificates must be send by the server to make it possible to build a chain of certificates ending in a root certificate.

  • Firefox for Mac does not recognize a valid SSL certificate

    Firefox for Mac does not recognize the SSL certificate that is valid for this site, I got: https://www.georgeglazer.com. It gives a warning "not reliable." However, the Firefox for Windows does not give a warning. This happens even if I clear the cache and it happens in the Mavericks and OS of Yosemite. The certificate is up-to-date and with Comodo. Firefox for Mac is now the only browser producing these errors (v. 39, put updated) - Internet Explorer, Safari and Chrome are not. Our hosting provider has said it's probably a browser issue, perhaps having to do with intermediate certificates in Firefox being obsolete. I really hope you'll solve the problem, as it's annoying for us when we're going to do right by our customers and pay for the SSL certificate. I have attached a picture of the warning and the other from what you see on a PC: a pop-up that says it is a verified SSL certificate and gives details about the issuer, the period of validity, etc.

    COMODO should you sent a link to download the file 'bundle' containing the intermediate certificates. Who needs to go in the same directory as the certificate of your site. If you are using a control panel, your host can probably help with this process. And if you bought through them, shame on them for not taking care of this for you already!

  • How to accept a new ssl certificate in Thunderbird?

    7.15.15
    I can't get or send emails on my cell phone two days ago.
    - Neither the "Configuration Options for certificates" worked to bring in the certificate that I use that allows you to send and receive e-mail. Under the "Digital Signature" or "Encryption" when I press "Select" to select a certificate, I get the pop-up message "Certificate Manager cannot locate a valid certificate... ». When I press 'View certificates' certificate that I use is listed under 'Servers' and the 'authorities' and is up to date.
    -In addition, under Tools - Options - Advanced - certificates for: "when a server requests my personal certificate", I selected "Ask Me every time" and left "query OSCP responder servers to confirm...". ', the box is checked.

    I think that this problem is bound to accept a new ssl certificate has been recently renewed. I've never had this problem before. How to start accepting a new certificate?

    Thank you.

    No you can not communicate with the server using a common product of Mozilla. In a short while you will not be able to co interact with it with any product. The operator/administrator of the server needs to fix their server to issue certificates 1024-bit or better. Or stop using TLS.

    The best explanation of this change and it's because I've seen is here https://weakdh.org/
    (right at the bottom of the page is what you need to do stuff)

    In essence, that the server does not have a security flaw serious patched and Mozilla products have been modified to not interact with servers that have not corrected the vulnerability. Vulnerability leaves you open to man in the middle attack on piracy.

  • How can I set up email when the field on the SSL certificate does not match?

    I am a customer of Dreamhost and don't know if our situation is unique or not, but both smtp and imap are "mail.example.com" even if the SSL certificate belongs to ' *. DreamHost.com'.

    I was not able to set up the email on my flame app because I get the following error:

    > Could not establish a connection with "mail.example.com". There may be a problem with your network or server.

    I think the problem is the lag of domain name, but I can't find a way to accept the certificate.

    Hello!

    According to the official DreamHost wiki site , you can try this (cut-and-pasted from the page). If it doesn't work, there are still other options available on the page.

    To connect to the mail server using the name of the server dreamhost.com instead of messagerie.votre_domaine.fr.

    Use the following steps to determine the name of the server to use:

       In the DreamHost Control Panel
       Click "Account Status" in the upper right hand corner
       Look for the "Your Email Culster:" at the bottom of the list.
       Find your cluster in the table below.
       Use the server name for the incoming server in your mail program.
    

    Name of Server Cluster e-mail
    homiemail-sub3 sub3.mail.dreamhost.com
    homiemail-sub4 sub4.mail.dreamhost.com
    homiemail-sub5 sub5.mail.dreamhost.com

  • Thunderbird does not recognize a self-signed SSL certificate

    Dear support,

    I have a very strange problem that I don't understand.

    I run a server ISP offering IMAP and TLS/SSL HTTPS encryption. Both services use the same SSL certificate issued by RapidSSL/GeoTrust Server edward.ennabe.de

    When I open an https connection to the server, Firefox correctly solves the certificate chain and use the certification authority root Equifax (which is correct).
    However, when I try to connect to a mailbox via Thunderbird, all I get in the hierarchy of certificates is my server edward.ennabe.de. I don't think that it's "working as intended", or is it?

    Is something wrong with my Thunderbird or My Dovecot configuration? What is really strange that firefox recognizes it correctly.

    Thanks in advance

    Kind regards

    ZeroEnna

    In Thunderbird, click the 'Détails' tab in the display of the certificate.
    See all certificates of CA listed in the field "Certificate hierarchy" also installed in your Thunderbird certificate store?
    When checking this look for the tab 'authorities '.
    If there are no certificates listed in the missing chain in the Thunderbird certificate store (for some reason any), you can try to export it in Firefox and import them into Thunderbird.

  • SSL certificate not used for Admin Server connections

    I have a GoDaddy SSL certificate installed on OS X Server 10.11.4. It works very well for the web server (https). Connection via Server.app off-site, produces a warning SSL and self-signed certificate. There is a related error regularly in newspapers:

    Any suggestions? I reinstalled the cert...

    You must raise the.app of 3rd party certificate.  Follow these steps:

    1: Open Keychain Access.

    2: select the system Keychain in the keychains list.

    3: find the preference of identity com.apple.servermgrd and double click it.

    4: select your SSL certificate 3rd party in the contextual menu of preferred certificate.

    5: Press the button Save changes.  You will be asked to authenticate.

    6: restart the server or restart the process of servermgrd to activate the changes.

    Now when you connect to the server from a remote device using.app, sign in using your valid 3rd party SSL certificate and avoid mistakes.

  • The e-mail application does not connect to the Dreamhost servers. Perhaps because of how they configure their SSL certificate for their subdomains.

    http://wiki.DreamHost.com/Certificate_Domain_Mismatch_Error

    Certificate SSL of Dreamhost for their mail servers only at one level of subdomain while many of their clusters of e-mail exist on a second level subdomain. In my view, this translates into an error message 'bad security' of the e-mail application.

    I contacted DreamHost and they say they are unable to solve this problem, or that they will allow me to install an SSL certificate on my virtual domain pointing to my cluster e-mail (even if I had to buy a).

    I understand, it is possible to manually add certificates via adb in a way similar to this: http://www.pending.io/add-cacert-root-certificate-to-firefox-os/

    However what I read this: 1. does not work on the ZTE Open 2. Can only fix only navigation not the web mail client.

    Is there any option that is available to me short of switching hosts?

    Fabian,

    Are you familiar with Firefox OS? The reason why I say this is because the e-mail client cannot create an excaption certificate. In fact, it's design. It's design: https://wiki.mozilla.org/Gaia/Email/Features#Security

    This request for support to Mozilla was placed specifically for the product Firefox OS, for which there is only a single mail client.

    That said many people in the Mozilla Bugzilla, have been able to show me how to find another alias for those servers that actually works and in fact corresponds to SSL certificates. Although Dreamhost support could not provide me with any such information, and such information is not actually in the DreamHost wiki.

    I have a repeated insistence of Dreamhost possibility I should just live with the exceptions of SSL certificate, when there is real existing valid server names to match the certificates in question, silly.

    The fact that you post this solution for one product, so that it is not yet applicable beyond useless. It serves to muddy waters.

  • All the sites SSL Web I visit displays the message "this connection is untrusted" and shows me a false SSL certificate for a different domain name.

    When I visit a Web site that requires SSL I displays the message "this connection is untrusted". Any Web site that I visit, it's always exactly the same message and the same SSL certificate that she is no longer valid for www.thawte.com

    When I click "Add the Exception" on a Web site and view the certificate, it is exactly the same certificate with the exact same serial number.

    I had a similar problem with Internet Explorer showing a 404 error when I visited SSL protected pages but to do a restore of the system a month ago to correct this. All other bowsers are / were very good.

    I installed Firefox 3.x month last to test something that is when the problem started. I have since uninstalled Firefox 3.x and reinstalled the latest version. I deleted all the preferences/settings, disabled modules and reinstalled many times. I did a Windows system restore to before that the problem started with no luck.

    The time / Date on my computer are correct. I have no firewall other than the windows one. I had no antivirus (netbook) until I installed a (Avast) yesterday to see if a virus was causing issues (found nothing). This problem arises on any internet connection (tested to work and home).

  • Impossible to update SSL certificate for Mail account

    My SSl certificate has expired. I bought a new one installed and all other mail client works fine... except this junk called Mac Mail. Now, I can't check my email at all.

    I have 14 accounts on the same server. One account was asked to accept the new certificate (hostname mismatch). All other accounts are now with one! and "taking into accounts online" does nothing. Remove the SSL account does nothing. Remove the old certificate to keychain does nothing.

    It is a valid, rather than a self-signed certificate.

    So while I'm reconfigure everything on a real email client, anyone happen to know how to solve this problem? Every solution proposed elsewhere (other discussions, forums) do not work. Short to delete all accounts and recreate them will work hoping, this seems to be a lost cause...

  • Impossible to get websites to use respective SSL certificates

    Mac OS 10.10.5

    Server 5.0.15

    I have a question where the default web site ("Server (SSL) Web site" ") is in conflict with the SSL certificates for my three other SSL sites.

    The configuration of my website (Note: server IP is 192.168.1.100)

    • Web Server SSL (all IP addresses) site - cert for domain1.com (work)
    • Domain1.com (192.168.1.10) SSL - cert for domain1.com (work)
    • Domain2.com (192.168.1.20) SSL - cert for domain2.com (cert draws for domain1.com, invalid identity)
    • Domain3.com (192.168.1.30) SSL - cert to domain3.com (cert draws for domain1.com, invalid identity)

    My DNS records:

    • Primary area - Domain1.com
      • A: Domain1.com 192.168.1.10
      • NS: Domain1.com
    • Primary area - Domain2.com
      • A: Domain2.com 192.168.1.20
      • NS: Domain2.com
    • Primary area - Domain3.com
      • A: Domain3.com 192.168.1.30
      • NS: Domain3.com
    • Reverse zone - 1.168.192
      • PTR: 192.168.1.10 Domain1.com
      • PTR: 192.168.1.20 Domain2.com
      • PTR: 192.168.1.30 Domain3.com
      • NS: Domain1.com
      • NS: Domain2.com
      • NS: Domain3.com
    • Reverse zone - 100.1.168.192.in - addr.arpa
      • PTR: 192.168.1.100 server.domain1.com
      • NS: server.domain1.com

    Whatever the cert is selected for the default Web site apply to all SSL Web sites. The only way I can force everyone to use their respective certificates is to set the IP address of the Web site to be the same as the IP of the server (in this example 192.168.1.100). It works, but which prevents the work Profile Manager.

    I'm 99% sure that I have my DNS configured correctly (right now all a records point to 192.168.1.100 as a temporary solution), but I'm willing to take another look, if someone has a suggestion clearly and concisely. Ideally, each DomainX.com would have an IP de.10.20 et.30.

    So how can I do all three Web sites use different IP addresses AND their respective certificates? Is this possible?

    (I appreciate any suggestion at this stage. This question is impossible to find an answer anywhere on the internet after about 9 months of research).

    Solution for someone who comes looking for this problem!

    After talking to the Apple Enterprise support:

    The site services will assuming that you only have one certificate for all Web sites. Unless you want to really roll up your sleeves and get down and dirty with the Apache configuration files, you must have a valid certificate for all areas, you use AND give each site its own IP address.

    When configure you your certificate, the host name must look like this:

    Server.Domain1.com (this is the name of your common)

    *. Domain1.com

    *. Domain2.com, etc..

    I used a StartCom certificate class 2 IV SSL ($ 59 / year).

    Then, assuming you know how to import a verified certificate, use it for all services that need and all the websites you want course (why wouldn't you use https, anyway?)

  • How to clear all SSL certificate exceptions?

    I want to erase all certificate exceptions, in other words, to return to the original set of SSL certificates secure by default. I found the Manager certificates and its large lists of things trust, but I don't know which of them bundled with Firefox and which of them were added by me at some point in the past. How can I do this?

    Rename or remove the file cert8.db in the profile folder to delete all intermediate certificates that Firefox has stored by visiting secure Web sites.

    Certificates roots of build-in will display as "Builtin symbolic object" and intermediate certificates stored as 'software security device.

    Rename or remove the cert_override.txt (cert_override.txt.old) file in the Firefox profile folder to remove any permanent exceptions that you have saved.

  • Pre complains about SSL certificate on the exchange server

    Hello.  I just got a pre and tries to set up to communicate with an exchnage server.  Pre complains and will not set up the connection with this error message: «"SSL certificate error.» Is the date and time correct? ».  The date and time are correct, but the server is running a self signed certificate.  This causes no problems with iPhones that use a lot of people here.

    How can I fix it?  It is not all parameters for this problem.

    I spent the weekend trying to test and understand what was going on.  I found that if I nominated the e-mail server (name after HTTPS: / / in Setup) the same as the name of certificate displayed in the Certificate Manager (Launcher > Device Info > more info > Menu > Certificate Manager), the error should disappear.  The problem for me was that the name of cert in cert Manager was different from address of mail server (in my case server. [domain .local] instead of mail. ([Domain_name] .com).  The transformation it seems to use is:

    (1) find the certificate...

    (2) CN is HTTPS: / / in the installer?

    (3) If no, use error 'Verify the certificate, date and time not correct' (or whatever it is) - If Yes, go to HTTPS: / /.

    (4) Exchange requires safety pin?  If no, proceed to synchronize - if so, use error "unsupported of security policies.

    So I looked more closely CERT and it held several common names (CN) for the cert.  It seems that ANY OTHER DEVICE can filter through the list of common names, and use the one that works.  The Pre uses only (whether first or last, I don't know).

    So, there are two options for the certificate problem (I guess the 3rd is that you can return the phone):

    FIRST SOLUTION

    =====================

    (1) check the name of cert in cert Manager.

    (2) if it is a name that can be resolved DNS (i.e.  [mail]. [mywebsite]. [com]) then change this setting in your exchange installation program in the mail server field beside the HTTPS: / /.

    This will only fix it if your COMPUTER administrator has with permissions on the used field.  It is possible that an alias is used on other areas

    SECOND SOLUTION (as I have done)

    =================================

    (1) ensure that your Certification Authority is installed.  You can do it by clicking START > ADMINISTRATIVE TOOLS > CERTIFICATION AUTHORITY - OR - on a computer on your network using IE/Safari/Firefox and typing http://server/certsrv.  If the page is found, then you are installed, if not, then you will need to have installed.

    NOTE: SBS 2003 WILL AWARD A CERT TO THE IIS WITHOUT THE ROOT CA.  THIS SEEMS TO BE THE PROBLEM WITH THE AUTO CERTS GENERATED I HAD

    (2) If you have not installed it, go to this topic, it is well written to get step by step instructions how to install, create demand for cert, create the cert and install the cert (it took me about 30 min).   http://www.MSExchange.org/tutorials/SSL_Enabling_OWA_2003.html

    NOTE: IF YOU ALREADY HAVE A CERT ON IIS, YOU NEED TO REMOVE IT AS IT IS "DEFECTIVE" CERT BEFORE YOU CAN REQUEST A NEW CERTIFICATE.  YOU MAY BE ABLE TO REINSTALL OVER THE NEW CERT, BUT I DON'T KNOW

    (3) open https://mail.domain.com/exchange on your computer - display details of the cert and save the file on your desktop - if you are using a laptop, you can also install it on your laptop to use for use outside the Office (this is also a good back-up that you can use to get more later if needed again).

    (4) plug your pre in USB mode.

    (5) slide the cert and unplug the USB cable

    (6) go to cert Manager

    7) tap on the icon of "Sun" at the bottom left

    (8) press on the new file cert that you save in USB mode

    (9) to confirm that the new cert appears with the name of the correct mail server

    10) go to the e-mail program and configure the exchange account

    The above will create a REAL root cert (not IIS domain root Cert) that the Pre can work with.

    Really, I don't know that how/why Palm overlooked this possibility because they claimed so-called does not want to sell to companies who need strict security requirements.  For me, it means a small / medium company that has limited IT supports (according to the needs, pay as you or green guy with limited knowledge).  Then, why they test the GER in this environment, I'm not sure.  I bet they were tested on their own network, which has all the correct methods, best practices for the management of cert.  I guess it's like the developers that they have offended and almost lost their support until turned it over and said: 'sorry, we really want make you programs for our platform WebOS. ".  We've just been paranoid for so long salivate us when the bell rings. "They just didn't beta test this well enough.  The sad result of this is that Sprint will have to address all of the sheets because this certificate simple reading process was given only minimal recognition capabilities.

    But having said that - I'm now completely in love with my pre!

    I'm happy to try to help if you need it.  I found a lot of the forum of solutions were not enough detailed, so do not hesitate to contact.

  • Invalid SSL certificate

    My company uses Citrix Receiver to allow us to connect to the House to work.

    I installed the latest version of the plug of the receiver in and all have El Capitan, I don't go through safari but rather connect by Miss this step and launch citrix directly, pop in my user name, password and rsa token details.

    At this point, I see a message invalid SSL certificate.

    Any ideas how I can check whats wrong, are the certificates stored in the keychain?

    Howdy John!

    Looks like you have a SSL certificate, which plays well with El Capitan. I would use the troubleshooting for this in the following article to help you here:

    OS X El Capitan: If your certificate isn't being accepted

    If a certificate is not accepted, it may have expired or it may be invalid for the way in which it is used. For example, some certificates may be used to establish a secure connection to a server, but not for the signing of a document.

    The most common reason that a certificate is not accepted, is that the root CA certificate is not approved by your computer. To have your computer trust a certification authority, you must add the certificate authority to a keychain and set the certificate of trust setting.

    1. If an application (e.g. Safari) displays the root certificate of the CA as part of the CA message, drag the icon of the certificate root on the desktop.

    2. Drag the certificate on the Keychain Access file, or double-click the certificate file.

    3. Click menu Keychain, choose a set of keys, and then click OK.

      If you are prompted, enter the name and password for an administrator on this computer user.

    4. Select the certificate, and then choose file > read the information.

    5. Click the trust triangle to display the certificate trust policies .

    6. To override the trust policies, choose trust settings that you want to replace in the pop-up menus.

      For more information, see certificate trust policies.
