qBittorrent 3.1.8
Ubuntu 14.04

Got qBittorrent working with torguard with much help from sledgehammer999.

Now that I've been using it for a while I can summarize the issues that I've noticed.
In fact, the problems are so persistent that qBit is more or less just being used as a search tool.
Sometimes I'm able to do a download but most often I just download the torrent or copy the magnet link and hand the actual downloading off to Deluge.

Here's a summary of what I experience using qBit:

1) When I double click a torrent in search (or click download) nothing happens.  Then after a healthy delay (as much as 15-30 seconds), the torrent will appear in the transfers tab.

2) Then qBit will try to find a working tracker.  If I'm lucky it will find a tracker but most often not.  If it does find a working tracker, it will usually download OK or stall.  Most often it will not find a working tracker (http or udp).

3) If/When it fails to find a tracker or stalls out as mentioned above, I copy the magnet link and paste it into Deluge where 99% of the time it immediately finds a tracker and starts a download.  And yes, Deluge is also configured to use the same proxy (torguard).

So, needless to say, this is a real PITA but I guess I'm happy to have the search capability at least.

Are they both on different listen ports?

Actually, I'm using a range of ports (54540-54550).  Deluge allows for a range.  QBT is using 54545.
I don't usually run them simultaneously though I have and they seem to coexist (each was downloading a different torrent).
