setting up a new computer, trying to set up my gmail account on Thunderbird I get this message... Secure connection failed

' live.mozillamessaging.com uses an invalid security certificate.

The certificate is not trusted because the issuer certificate has expired.

(Error code: sec_error_expired_issuer_certificate)


   *   This could be a problem with the server's configuration, or it could be
     someone trying to impersonate the server.
   *   If you have connected to this server successfully in the past, the error may
     be temporary, and you can try again later.

  Or you can add an exception…

just a screen capture as you posted in your initial topic is what is needed. I am guessing, but I think the issue may be it is issued by your antivirus.

you may have hit it. this system has Bitdefender from NetGear. the old sys has AVG. I don’t know bitdefender well enough to know where to look or change

j8ust disable it (windows defender will kick in) and see how things change or don't change. I do know bitdefender scans using self signed certificates on encrypted connections which is what the connection to get mail is almost exclusively these days.
