I installed the latest Ubuntu 18.04 and am trying to connect to our in-house XMPP server (which is quite old and I have no access to) with Pidgin like I used to.

But I'm unable to connect... Getting an SSL Handshake Failed error.

This is what I get in the debug window:

Tried every possible account setting... but nothing seems to work...

Any suggestions ?

  • This is a non-programming question which belongs on Super User. I suggest posting your question there, and getting a packet capture of the SSL handshake using tcpdump or wireshark. Good luck! – MattJ May 04 '18 at 11:45

I have solve the problem like this:

Modules -> NSS settings ->

Min version: 1.0 Max version: 1.3 (max available)

And check all crypto modules.
