UUCP connection "Timed out in chat script"

I already have an installation on one of my machines in which I can
connect to multiple other machines (both Debian) via tcp and Taylor UUCP.

Now I want to make a connection between my notebook and my server, and for
some reason the connection eludes me so far. It clearly connects (via ssh
pipe), but then times out in chat script according to the log. This
happens from both sides, and I cannot see any issue with the configuration
on either side.

Is there a way to get more information as to why it times out? Or what
exactly it is doing when it tries to connect? So far I have not found any
logs that get into it deeper than the normal uucp Log file in /var/log/
uucp.
