Why isn't Transmission working?
12,601
Solution 1
Running sudo ufw allow out 6969/tcp
fixed my problem.
By opening port 6969(TCP) you allow the torrent software to communicate with the tracker.
Solution 2
503 Service Unavailable
and 504 Gateway Timeout
are tracker server responses.
Transmission did connect to the tracker but it failed to respond correctly. It's either overloaded or down. Try another tracker or torrent and see if it helps.
See List of HTTP status codes.

I'm using the latest version of Ubuntu and Transmission.
According to Transmission, the file I am downloading has 0 peers and is idle, even though there are a few peers seeding it.
Here's a batch of error messages from Transmission's log:
> Could not connect to tracker. Tracker gave HTTP response code 503, 504
This is the firewall's status:
> To Action From -- ------ ---- 51413/tcp ALLOW Anywhere 51413/udp ALLOW Anywhere 51413/tcp ALLOW Anywhere (v6) 51413/udp ALLOW Anywhere (v6) 51413/tcp ALLOW OUT Anywhere 51413/udp ALLOW OUT Anywhere 25,53,80,110,443/tcp ALLOW OUT Anywhere 53/udp ALLOW OUT Anywhere 67,68/udp ALLOW OUT Anywhere 5050/tcp ALLOW OUT Anywhere 51413/tcp ALLOW OUT Anywhere (v6) 51413/udp ALLOW OUT Anywhere (v6) 25,53,80,110,443/tcp ALLOW OUT Anywhere (v6) 53/udp ALLOW OUT Anywhere (v6) 67,68/udp ALLOW OUT Anywhere (v6) 5050/tcp ALLOW OUT Anywhere (v6)
Also, Transmission says that port
51413
is open. -
user46546 over 12 yearsThanks. I tried this torrent(releases.ubuntu.com/11.10/…). Transmission still says that it's idle and has 0 peers. And the message log reads, "Could not connect to tracker.".

user46546 over 12 yearsBoth trackers were already added in the torrent file. Still nothing.

Alexandre over 12 yearsIt is nice you got Transmission working but it would also be nice that you explain what that command does so others can take advantage of your finding as well.
