I have never used LiveJournal to log-in, only gmail. Has LiveJournal ever worked for you previously?

I think someone reported Jabber no longer worked several years ago but I would need to double-check that.

WSHR being Firewalled can make a difference in regards to connecting to 'Friends', but in regards to logging-in to the mail service, it would depend upon exactly how badly firewalled. In theory I suspect light firewalling should not make a difference to logging-in.
