Certificate with HTTPS sites problem

Hey. Im having a problem on all sites start https. When I try for example connect https://addons.mozilla.org/ , I get this:
http://i.imgur.com/2zPE8.jpg

I already tried to restart the computer, start FF without addons, reinstall firefox etc, but still have the problem. With IE, everything seems to work fine, but I would still use firefox.

What security (firewall, antivirus) software do you have?

Some firewalls monitor secure connections (https) and send their own certificate instead of the certificate of the Web site.

If you have ESET and then see:

  • ESET setup-> Advanced Configuration-> expand web and email-> SSL shaft
  • SSL protocol: do not scan SSL protocol

You can retrieve the certificate and check details such as WHO issued the certificates and the expiration dates of certificates.

  • Click on the link at the bottom of the error page: "I understand the risks".

Let Firefox recover the certificate: "Add Exception"-> "get certificate".

  • Click on the "view..." button. "and inspect the certificate and the Coachman, who is the sender.

You can see more details like the intermediate certificates that are used in the details pane.

  • stagewebview problem with https and invalid certificate

    Hello

    I use StageWebView to display a HTML with https and an invalid certificate, and I find a very strange error. It works well when I install the app on my iPad, but if I force to close the application, and then I open it again, the html page cannot load even if I close and open the application (do not force this time)


    Can someone help me please?


    Thank you

    I solved it with a valid certificate.

    I think that apple does not support the invalid certificate.

    Thank you

  • I have a problem of "Secure connection failed", access to an HTTPS site.

    I have a problem of "Secure connection failed", access to an HTTPS site. It is of this type:

    Your certificate contains the same serial number for another certificate issued by the certification authority. Please get a new certificate containing a unique serial number.

    (Error code: sec_error_reused_issuer_and_serial)

    OK, I have not read the support article carefully enough - it even says that this dialogue cannot be exceeded by adding an exception.
    you are most likely right that this problem arises because the same cert is used for different sites. this support article describes a work around, but it is probable, not applicable to your situation, since you would also have to remove the certification authority and which would create all sorts of problems as your production site will tend to choose an a valid CA certificate.

    Please contact your IT department or the problem of certificate on two different servers or to allow you to run a version of portable firefox where you can mess with the certificate store and the authorities of trust in order to access the test server.

  • Problem connecting to https sites

    From now on for all sites with https connection, I got message on all pages of google.

    Also you can add this message as an exception

    www.Google.com uses an invalid security certificate.

    The certificate is not trusted because the issuer certificate is unknown.
    The server may not send the appropriate intermediate certificates.
    A certificate of origin additional should be imported.

    (Error code: sec_error_unknown_issuer)

    Another site with https, if add exceprtion in the console, I saw exception

    This site uses a SHA - 1 certificate; It is recommended to use the certificate with the signature algorithms that use stronger than SHA - 1 hash functions. [Learn more]

    As for the site with addons

    services.addons.Mozilla.org uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server may not send the appropriate intermediate certificates. A certificate of origin additional should be imported. (Error code: sec_error_unknown_issuer).

    Now, you can not use FF.

    Yestreday, everything was fine.

    Sorry to hear about these worries.

    This often affects users who have security software that filters the secure connections, such as Avast, BitDefender, ESET or Kaspersky. These products brought to 'false' certificates in Firefox to intercept and decrypt your navigation. If you (1) was updated to a new version major of this product, or (2) use the feature reset and updating Firefox, Firefox can trust is no longer in your security software to generate these false certificates then you set Firefox up to work with her again.

    But another cause can be malware which hung a ride with some software you installed recently.

    To try to find the cause, on the error page, please develop the third section ("I understand the risks") and click on the button add exceptions. We will not actually save an exception again, but this opens a dialog with a button to display the certificate in order to verify the "who" or "what" signed the untrusted certificates. You can cancel from the dialog box add exceptions.

    For comparison, I have attached a screen where I packed the "distributed by" and "Hierarchy of certificates" information for this site. As your watch?

  • vRealize 7 - NSX Automation deployments fail due to problems of certificate with vRealize Orchestrator

    Hello community,

    After you have installed the latest version of vRA, vRO, and NSX I run questions when you apply components that use components of the NSX. First of all: details of the version:

    -vRA: 7.0.0 (build 3292778)

    -vRO: 7.0.0.16989 (build 331003)

    -NSX: 6.2.1 (build 3300239)

    vRO plugin versions are delivered with the vRO version listed above with the exception of the plugin NSX, which has been updated to the latest version (1.0.3 published on 17.12.15).

    In the configured tenant vRO is configured as endpoint. I can check the data collection is running and working. I can see the plugin NSX for vRO runs the workflow 'create endpoint NSX' from time to time using the configured user of vRA VRO.

    In the configured tenant vRO is thus configured as server default for ASD vRO. Connection test is successful. When you save the config I'm prompted to approve the vRO certificate, which I confirm. Note that the thumbprint specified matches the footprint of the vRO certificate that I get during the visit of the vRO system on https://vro:8281. I am able to navigate the vRO vRA designer workflows, therefore: connection seems established.

    Within vRO the vRA COFFEE and plug-ins IAAS have been saved successfully. I am able to browse the inventory of plugin for both plugins.

    To solve the problem, I created a new unified plan within the design section of vRA with the following configuration:

    -Transport box: my area of transport configured NSX (checked: manual creation on this area using NSX works very well)

    -Routed res pol. Bridge: my reference for the dash cluster to use Pol

    -The only component dragged to canvas is a 'network and safety'-> 'On-Demand NAT Network' that uses a profile preset 1-to-many network as is "Parent network profile" without manual modification.

    -Note that, although there is a plan very simple example to illustrate the problem, it happens with any model that I have set up if any component is confgured requiring the NSX plugin for vRO.

    "Whenever I ask this plan, the request fails with the error message:" ","application [fa1e0689-0d06-4308-a914-e498c0d1fd99]: 404 not found "

    Looking in vCenter, NSX and vRO I can check that nothing is really trigged when you ask for the action plan.

    Consider the vRA /storage/log/vmware/vcac/catalina.log becomes very visible:

    com.vmware.vcac.iaas.vco.network.helper.VcoEndpointSelector.isEndpointAlive:88 -
    vRealize Orchestrator endpoint with url [https://s00-vro.my.domain:8281/vco] is not alive. 
    Exception message:> [Host name 's00-vro.my.domain' does not match the certificate subject provided by the peer (CN=s00-vro.my.domain, OU=VMware, O=My Company, C=DE)]
    
    com.vmware.vcac.iaas.vco.network.helper.VcoEndpointSelector.getFirstAliveEndpointByPriority:200
    - vRealize Orchestrator endpoint [https://s00-vro.my.domain:8281/vco] with priority 1 is not alive. Skipping.
    
    org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolv
    er.logException:189 - Handler execution resulted in exception: Endpoint not found. There are no vRealize Orchestrator endpoints that are alive.
    
    com.vmware.vcac.platform.service.rest.resolver.ApplicationExceptionHandler.handleHttpStatusCodeException:673 - 404 Not Found
    org.springframework.web.client.HttpClientErrorException: 404 Not Found
    ...
    ...
    ...
    
    

    Please note that I double checked the certificate. This is a self-signed certificate created using the 7.0 vRO new control panel, the one I get when you go to https://vro:8281. It is valid and the object (issed to CN) matches perfectly the hostname entered the ASD and endpoint configuration in the vRA. It is separable and time on all components of the server is in sync with the use NTP.

    Now, I even re-generated certificate and re-registered and rebooted all the components, but while I can see that the certificate has been updated all components I always get the same question.

    Never had this problem with the previous version of the NSX / vRA / vRO. I checked the documentation if nothing has changed here, but did not find what I'm doing wrong. Anythimg I'm missing here? Any bug?

    OK, this seems to be the issue. So put atleast to previous day since version ofvRO (cannot check if it's true for charges vRO 7 installs as well but it is probably) vRO 'control center' will generate certificates based SHA1 vRA love not for actions that use the endpoint in the vRA vRO. ASD seems to work without these problems.

    Sidenote: VRO upgraded installs will also come with SHA1 based CERT if they use a self-signed cert created by vRO. However: you would think that it is sufficient to recreate the cert using the control center. But it turns out it isn't, because it will generate a (new) based SHA1 cert.

    What I did to solve the problem:

    1. create a vRO SSH2 based certificate without the cert extensions, similar to the one that ships with built-in vRA vRO. I tend to use xCA for these jobs, but openSSL will do as well. The exact format required for the certificate of vRO is not documented, but I can make sure you need it like this: PEM certificate in key private and public including format PKCS #1, formatted as follows:

    -----BEGIN RSA PRIVATE KEY-----
    (Your private Key: your_vro_server.key)
    -----END RSA PRIVATE KEY-----
    -----BEGIN CERTIFICATE-----
    (Your primary certificate: your_vro_server.crt)
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    (Your intermediate certificate: intermed.crt)
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    (Your root certificate: root.crt)
    -----END CERTIFICATE-----
    

    I had problems when I used the key extensions so I would say you don't use and don't create a very basic cert without extensions V3, as indicated on the right of the image to my last post (ideally, you want to have a cert with the same properties as the cert is used by the device of integrated vRO vRA unless of course different CN) etc.).

    2. use the vRO control center located at https://your-externa-vro:8283 / vco-controlcenter / #/ and move to--> Orchestrator Server SSL certificate certificates. Use the action to import to import your PEM cert. It should tell you that you need to restart your device vRO. Then RESTART the device (for not just restart the service, this seems not be sufficient).

    3 al ' vRA remove the Endpoint vRO everywhere wherever it has been configured. Also, I removed the vRO to the ASD config just to make sure that nothings left.

    4 reboot the vRA power (IAAS can be left as what). I needed to do this because I have seen that the keystore at some point would keep beeing crushed by CERT vRA (?), I deleted it (AND I checked that they are deleted) reappears in the keystore after a while. After a reboot, the problem was gone, the keystore was clean.

    5. Add the configuration of endpoint and ASD vRO. Accept the certificate.

    6. the works.

    Therefore, while I have no more time to solve the problems more than I guess the problem is the SHA1 function certificate generated by the device of vRO. The internal unit is equipped with a SHA2 based cert that works and after that change the external device SHA1 cert in a basic cert SHA2 all works.

  • Problems with HTTPS and javascript widgets

    My HTTP site works fine, but when I switch to HTTPS, I get the following error...

    MuseJSAssert: Error calling the function switch: TypeError: E.split is not a function

    I have even tried to create a simple page with nothing else than a javascript widget, and I still get the error when you use the HTTPS version.

    FYI - I upload my pages using the 'upload to the FTP host.

    Muse and HTTPS is not compatible?

    It is more likely a problem with your server as a problem of cross-site script because the HTTPS protocol uses a folder or a different domain and browser security mechanisms as long as the server itself remove access to the script so. If there is a specific secure folder on the server, import is your files, otherwise, you will need to set an option in the web interface to allow HTTPs and normal HTTP access to your folder.

  • site with tables layout problem

    Hello

    I hope someone could help me with probably a stupid mistake on my part. It is with a site that I just started to work again; www.starprecision.com. I hope that you may think it is obvious as to why:

    1. There is a turn to the left for the 'home' page, "company > job opportunities" and "society > contact us" regarding other pages. This, for example, occurs in opera and FireFox. However not in IE7.

    2. the rectangular dashed line of the graphics will appear around the "prev" and "next" buttons when they are pressed in IE7 and FireFox, but not in opera.

    3. the recovery site will not yet be at the point in the Safari.

    4. I want to redo the site based on a model of css. We suggest a model for this site?

    Thanks for the tips, you should be able to provide.

    Take care
