Error trying to connect to remote server: proxy.jabber.org

I have the following error in my log:

I don’t understand… port 5269 is opened, I can ping jabber.org

but I see my @jabber.org contacts offline, though I can chat with them…

If i try pinging proxy.jabber.org, then it says there is no such host and i think this error comes because of that. Though i’m not usre where are you using this host.

Do not use warn.log, its absolutely useless and painfull. Turn on debug (in log4j.xml or temporary - in admin interface) and see whats happening in debug.log.

I think, this is SSL/TLS-related problem.
