Recently upgraded to FF 31 from 24 ESR. Now receiving an error when trying to visit an internal web page of mine. Secure Connection Failed An error occurred during a connection to xxxx.website.com:8443. SSL received an unexpected Server Key Exchange handshake message. (Error code: ssl_error_rx_unexpected_server_key_exch) I seem to recall needing to modify a setting in about:config to resolve this previously, but I can't seem to find this information anywhere. I've tried the following modifications in about:config so far. Changing all "ssl.dhe" entries to FALSE security.tls.version.max = 1 (I've also tried 2 here with no success) Hopefully somebody here has run into this before and can lend a hand. I appreciate any help!
