Trying to load a secure website, firefox says "Secure Connection Failed: Peer's certificate has an invalid signature."

Posted

I need to get on this website, which only allows Firefox and Safari for Mac OSX, but since I upgraded to the latest Firefox update, this is the message I get:

Secure Connection Failed

   An error occurred during a connection to teleserve.dlt.ri.gov.

Peer's certificate has an invalid signature.

(Error code: sec_error_bad_signature)


Help!

The site doesn't seem to be sending the correct intermediate certificate.

You can install this VeriSign intermediate certificate that works for me.

Question owner

I installed it by going into Firefox, ->Preferences-> Advanced->View certificates->Import (the certificate file). Then I restarted Firefox, and it is still not working. Any other ideas?
