I have set up an IRC account in Empathy - the default server is, of course, Freenode. Empathy tries to connect and after a few moments reports, "Authentication failed".
I have tried with and without a password (My nickname is registered with Freenode.).
What could I possibly be doing wrong?
Update:
I was able to connect when on another network. Could the problem be with my Verizon Mobile Broadband?
Possibly that username is already registered with freenode and therefore secured with a password. Have you checked if you can connect by using another nickname?
