| [15:56:06] Problem connecting to tracker - <urlopen error (110, 'Connection timed out')>
Does this imply there are too many connections for the initiation of the process?
That's a possibility but improbable. More likely is some connectivity issue for that machine that prevents it from getting replies from the tracker.
Which torrent link are you using? The .torrent file has the address of the tracker inside. The client talks to the tracker using HTTP, so you should be able to reach it with a web browser. We just need to determine the URL to the tracker.
You can use btshowmetainfo.py to dump out the contents of the .torrent in human-readable form. You can then plug the tracker URL into your browser. (It starts with "http://" and usually ends in "/announce".) If you leave off the /announce you can see the tracker's stats.
