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!

You can try to disable libPKIX support in Firefox, but it is not recommended to leave it disabled on the long run for security and vulnerability reasons.

  • about:config page: security.use_mozillapkix_verification = false

Note that support for the security.use_mozillapkix_verification pref to disable PKIX has been removed in Firefox 33.

Unfortunately, that didn't make a difference. Strange issue. I'm sure I've come across this issue before I just can't recall how to resolve it.
