Secure connection failed, error code: sec_error_bad_signature

I installed windows 10 today. Not when I go to sites such as amazon on google, I get an error.

'An error occurred during a connection to www.google.co.uk. Peer's certificate has an invalid signature. (Error code: sec_error_bad_signature). The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the web site owners to inform them of this problem.'

So boring, everything was ok until today. Bloody Microsoft! I have re-installed Firefox but that does not cure the problem. Am temporarily using Chrome that doesn't have the bug, I can buy things from Amazon and search in google and use my gmail and youtube accounts. Can someone help me please? Thank you very much.

Hey, please disable https scaning in avast:

  1. Open the Avast dashboard on an affected system.
  2. Select settings in the left side menu.
  3. Adopt a Protection Active.
  4. Click on customize next to the Web Shield.
  5. Uncheck the option "Enable HTTPS analysis", and then click ok.

  • Any way to fix a "Secure connection failed" (Error Code: sec_error_ocsp_unknown_cert)?

    Recently (I think the 30 Oct) I've been encountering this problem while trying to connect to the web site of Rooster teeth. I tried to clear the cookies and cache several times to no effect and suggestion of help page for the workaround with a click on "or you can add an exception...". "does not work because this button does not appear on the warning page more. I get only this error warning when you try to connect ( http://roosterteeth.com/home.php ) and only when you attempt to open a session, it's not pop up for anything else on the site or any other site that I went to. Any help on solving this problem would be greatly appreciated.

    Hello TSturtledove,

    1. In the address bar, type Subject: config and press enter. The subject: config "this might void your warranty!" warning page may appear.
    2. Click on I'll be careful, I promise! to keep the comments: config page.
    3. the next security.ssl.enable_ocsp_stapling to copy and paste into the search field
    4. Double-click on it to make it fake
    5. Close the page, exit firefox and restart.

    no doubt the problem is the web site, when the problem is resolved by the site, go back and put the parameter to true .

    Thank you

  • Unable to connect to google after installing windows 10 "secure connection failed".

    I installed windows 10 today.

    now, every time that I can't get to google/youtube to firefox, internet explorer and opera.

    I get this error:

    "Secure connection failed".

    The connection on www.google.com while the page is loading.

       The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
       Please contact the website owners to inform them of this problem."
    

    I would appreciate help, google and youtube are rather important

    Sorry for the delay, long day away.

    With this many cross-browser issues, can you confirm that your system clock date, time, and time zone are all correct? SSL validity checks are time sensitive.

    If you see a globe, I think that you are unable to use an HTTPS address. Usually Firefox displays a padlock or a "!" icon in the shape of triangle on a HTTPS address depending on whether the certificate withdraws or has a problem.

    Is there a code in parentheses, separated by underscores in the error page? If so, could you copy and paste this code.

    This indicates that the site is by default an obsolete encryption encryption algorithm that is vulnerable to the attack of 'Blocking' which was in the news earlier this year.

    You can turn off these old present in Firefox to try to force the site to his game. Here's how:

    (1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

    (2) in the search above the list box, type or paste dhe and make a pause so that the list is filtered

    (3) double-click the preference security.ssl3.dhe_rsa_aes_128_sha to true to false (disable Firefox to use this encryption)

    (4) double click on the security.ssl3.dhe_rsa_aes_256_sha preference from true to false (disable Firefox to use this encryption)

    Then try your payment site. Any improvement?

    The only reason I installed it is because a University site, I need to use requires Firefox (my IE 10 is not compatible apparently). This is the MOST useless browser I've ever tried! I mean common SERIOUSLY? I do not have the settings even modified, installed add ons, or anything like that! So what is the point of this browser, if you need to be a computer WHIZZ to make repairs before you can use? OMW!

  • 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.
