ssh -v <host>
or even
ssh -vv <host>

would give you considerable information on which phase of the process is
hanging.

You could also crank up the logging for the server side in [probably]
/etc/ssh/sshd_config to see what it thinks is happening.  You did check
the logs, right?

And, yes, it could be the server trying to do a DNS lookup.  Does DNS
resolution work on the jail?  If it is broken and you don't want to fix
it, start fiddling server side settings such as UseDNS.
