Cannot access sites like invalid security certificate,

Similar Questions

• Firefox wrongly think that my site is using an invalid security certificate... clues?

  I recently installed a security certificate on my site.
  I tried different controllers of ssl and certificate seems fine.
  Firefox, however, don't like him and displays a warning page that says:

  www.Academi.pl uses an invalid security certificate.

  The certificate is not trusted because the issuer certificate is not approved.

  (Error code: sec_error_untrusted_issuer)

  This happens on Windows, Mac and Linux computers in my office.
  I also received a number of reports from users of the site who are experiencing the same problem.
  It seems that the problem does not occur in firefox 7.x, but I have to check properly.

  Anyone know a solution to this? I tried to remove the certificates manually in preferences, but it did not help.

  It worked for me! I had given up everything, but when I received this reply in my inbox this morning. I was skeptical at all first, think something so simple could not possibly solve all my problems... He did! Sometimes simple is best. Thank you all for the answers and help for this problem!

• When I visit a site, firefox reports invalid security certificate, but does not add an exception

  When I visit a site that has an invalid security certificate, my mobile me has a nice little dialog box telling me that the connection is not reliable and allowing me to view the site by clicking on ""I understand the risks"my office however shows a completely different dialog box." It is a simple dialog with a title of "Alert" and said... use a security not valid certificate... I don't trust blah blah and an ok box so I can never continue on the site.

  You can see it at https://www.dropbox.com/s/su6fpyimwqk3f5x/Screenshot%202014-09-19%2014.13.01.png?dl=0

  I use Firefox 32.0.2 under 64-bit Windows 8.

  Suggestions will be welcome.

  You can check the preferences of browser.xul.error_pages on the topic: config page.

  • Browser.XUL.error_pages.enabled = true

  You can open the topic: config page via the address bar.
  You can accept the warning and click on "I'll be careful" to continue.

• invalid security certificate

  When I connect to a site with a self-signed certificate, sometimes I get: "{site} uses an invalid security certificate." I can add an exception for self-signed certificates, but what does it mean when the security certificate is not valid.

  Some sites are just security certificates that have expired. So if you connect to this website, it will tell you that its a "security certificate not valid." It simply means that the owner of the site must renew its certificate.

• Unable to set IMAP account due to invalid security certificate - error 4010

  Hello I just got a new TouchPad and have updated the OS to the latest version. I try to set up multiple e-mail accounts and am having a problem with an IMAP account. I already put in place two POP accounts without any problems. But when I tried to set up a connection to the account of my work (IMAP) I wasn't able to do. He told me that the security certificate is not valid with the 4010 error.

  I did some research on the Board of Directors and have tried the following:

  (1) used the web browser to sign on my webmail from work, he complained the untrusted certificate and I said to add the exception and TouchPad Certificate Manager confirmed the certificate (webmail.myworkplace.com). This did not help the e-mail client.

  (2) someone suggests to send the certificate by e-mail attachment and open it. So, I exported the certificate through firefox (as X.509 - PEM certificate) to the POP account that I had put in place. The mail reader didn't know what to do with this attachment and will not open it. I renamed the file in .txt and the mail reader just showed me the text content. So no luck there.

  I have an iPod touch and I had no problem whether to set up my account to work with the native mail on this device reader and I do not know why the TouchPad also gives me a hard time.

  I'd appreciate any help in this. Thank you.

  Just a friendly reminder that I'm still unable to setup email on my TouchPad due to error message...

  Hi Zippy1970,

  Sorry, that took me so long. I ended up having to install openssl in order to display the certificate, but once I did, the issue jumped immediately.

  There are 2 problems with your certificate

  1. It is self-signed (this isn't a problem, there's just one additional configuration step involved)
  2. He was assigned to the wrong domain. Right now, the certificate is awarded to "localhost". This is not the area in which your TouchPad uses to connect to the server that is why he makes the mistake of certificate

  To make this work, you need to create a self-signed certificate that uses the correct domain name (the CN value must be the same domain name that you have sent me in private message).

  Also, you need to add this certificate to your TouchPad (because it is self-signed). The last part is pretty easy, just copy the certificate file on the touch pad using USB drive mode, and then open the Certificate Manager and the new certificate. To access the Certificate Manager:

  • Info on the open unit
  • In the main Menu on the left, select Certificate Manager
  • Press the Add button
  • Select your certificate

  Once this is done, everything should work for you.

• Cannot access site BI Publisher by IE 8.0

  Hello
  
  Here is my BI Publisher site: https://slc04wjk.us.oracle.com:19718 / xmlpserver
  I am able to access it through firefox, but failed through IE8.0. The error in IE 8.0 is: "Internet Explorer cannot display the webpage".
  Is this a known issue? any solution?
  
  Thank you
  Miao

  Check the support matrix - BI Publisher does not support IE 8 on Windows XP! Tim Dexter himself reiterated that personally to me by e-mail. Can you believe that go to such length to integrate with Microsoft, Oracle products, but cannot support its main browser? It's really more an indication of how much Microsoft adheres to the standards of the web.

• Cannot access site of firefox or google chrome on linux but can virtual XP on the same machine

  Run firefox 3.6.24 under Fedora core 14 64-bit. Could not load certain pages of the website with firefox or google chrome schoolfusion. I do not found Server error. On the same machine a virtual XP with IE or chrome can access the site. I checked the release of wireshark and the query is DNS as well as a good answer to the query or the dns returns the correct ip address. So I don't understand why the server error. On the same website, a link that works starts with 2 identical DNS queries, both get identical answers. There are a few settings network under linux only?
  I have an internet direct connect without a proxy.
  I tried all of the suggestions under Server error.

  Thank you

  It is "fixed" now, it turns out that the problem was that URLS that wouldn't have. It's a dash followed by a period.

  What I still don't understand, is why the error message was not clear. He said that he could not find the server but it reported the entire string, including the... There was therefore no indication as to why he could not find the server. It was also strange that IE and google chrome in XP both worked.

• Cannot access Web sites but IE can

  I can't access a website using 7 FF. I get a popup that says "secure connection failed! XML.freecause.com: 443 uses an invalid security certificate. "Error code: sec_error_expired_certificate" and it won't let me close. I have to use CTRL/ALT/DEL to close FF. I can't even access the FF support pages (including FF comments) using FF. I had to use IE to submit this. IE has no problem opening the same sites.

  The security certificate for the domain xml.freecause.com has expired because it was not renewed in time.

  You most likely have an extension that tries to contact this server, and you will need to disable this extension until the site has renewed its certificate.

  Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions of the origin of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

• accept invalid server security certificates in Android 4 +.

  Hello

  I have an AIR application that calls a script https on a server. We have a security certificate valid server on our live server, but not on our development servers.

  Everything works fine on the server, with Android and iOS.

  On development, with Android 2.2/2.3 servers, an alert appears on my phone asking me to accept the invalid security certificate before I can continue. It is very good.

  I don't get the pop-up with 4 Android devices. Just to do not and gives me an actionscript 2032 Stream error every time. However, the same apk on a device Android 2.2/2.3 oldest still works.

  AIR iOS apps were never allowed to call scripts from server without a valid security certificate. I raised this issue in the forum of pre-release flash and said it was a known problem. Can someone confirm if this is the case with the 4 Android devices now too?

  Thank you

  Nick

  Seems fixed in AIR3.7.

• Cannot use https wesites due to certificate error

  There was an update to Windows 7 and an update of Firefox 27 today. Unfortunately, I didn't do one at a time.
  First thing I noticed gmail was not correctly display the graphs in the chat window. Then the Firefox Add ons link check - did nothing, just display "Loading Data" and never do anything. I went the Add-ons for my Firefox and it displays the error message "this connection is Untrusted. You asked Firefox to connect safely to services.addons.mozilla.org, but we cannot confirm that your connection is secure. »
  and
  "services.addons.mozilla.org uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. (Error code: sec_error_unknown_issuer) »

  There is no way to add a certificate exception, so I can't use the addons page. Other websites using the https protocol either do not display correctly or also display the error "this connection is untrusted". I've done almost all proposed on forums and FAQS: I have reset Firefox, I deleted the file cert8.db and other extension files in my profile. I started in safe mode, try a different profile. A clean installed Firefox 26, and I always get this error message.

  I've seen suggestions that had to do with a security installation, which I did not, could there be an equivalent of McAfee?
  I use a company computer and do not have control over the antivirus settings or the proxy.
  I had to install Chrome just to post this question as the button "Ask the question" did not at all on IE.

  Found the solution... Found in a place of info on authorities of certification and checked in Firefox, it turns out that those used by our company (Zscaler) was absent.
  I exported 3 Zscaler certificates of IE and then imported into Firefox. It's working now!
