I just upgraded to ubuntu 14.04 and updated transmission to 2.82

adrian@my-little-friend:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04 LTS
Release:    14.04
Codename:   trusty

adrian@my-little-friend:~$ transmission-gtk --version
transmission-gtk 2.82 (14160)

I noticed the all the torrents I'm currently downloading stopped and the transmission showed "Could not connect to tracker" while the internet connection is unchanged and I can browse internet and download normally.

I have tried re-installing, purging and re-adding the torrents but they bear no fruit. Installed other torrent clients too (qtorrent, deluge, ktorrent) same results.

Can anyone help me with this issue?

  • the output of ifconfig and iwconfig might be useful to add to your question. – Elder Geek Jun 12 '14 at 19:41
  • @ElderGeek Just added them as requested. – Hungry Hyena Jun 12 '14 at 21:59

UPnP seems to be correctly forwarding the port 51422 to your ip address. You might try configuring your router port forwarding manually.

It's also possible the tracker you are using is down. Can you ping it?

  • I can't ping the sites but oddly enough I can access it via web browser – Hungry Hyena Jun 12 '14 at 23:08
  • the trackers are often at a different IP address than the websites. You should login to the sites and ask about the trackers or check the trackers listed in your torrent files and see if you can ping them. or try adding a different tracker to your torrent files openbittorrent.com lists an open tracker and includes info on how to add a tracker to a torrent file. – Elder Geek Jun 13 '14 at 0:02
  • I added various alternate trackers but they shows same results "Could not connect to tracker" on the other hand, another machine on the same network has no problem connecting to trackers and downloading from peers. Could be I'm missing some libraries for network routing/connections? – Hungry Hyena Jun 13 '14 at 5:55
  • Look here: askubuntu.com/questions/293356/… and here: askubuntu.com/questions/406010/… I think you'll find these useful. – Elder Geek Jun 13 '14 at 13:17
  • Do you still have this problem? – Elder Geek Aug 2 '14 at 16:31
