I have a Problem with jitsi on Mac OS X (2.8.5426):
We have a company-internal jabber server with an RFC1918
address. Works well, other jabber clients can connect without
problems. Even an (older) version of Jitsi running under Ubuntu 14.04
But the Mac Version just complains that the connection failed.
tcpdump shows that jitsi is successfully resolving the domain part of
the jabber account name (A record) and thus gets the IP address of the
jabber server. But then, no traffic at all happens between the Mac and
the jabber server. Jitsi complains about a failed connection without
ever having tried. (Since there is no traffic, it can't be a cert or
Any idea what to check?
