rTorrent: "Could not prepare socket for listening address Already in use"

When I try to access rtorrent via the web ui, I receive a ‘no connection established’ error. When I try to run rtorrent via SSH I get the error above. I tried restarting the service ( sudo systemctl restart rtorrent@<user>.service ) and then display status ( sudo systemctl status rtorrent@<user>.service ). I get the following output:

I’m not sure what the issue might be. Do I need to change the socket rtorrent is listening on? If so, how do I do this? And why would it suddenly become unusable?

Just started getting this exact issue as well.

#3

If I remember correctly I got this problem when I wrongly set autodl port the same as rtorrent…

For me, I had to kill rtorrent processes, make sure systemctl was stopped for rtorrent, then reboot box and start rtorrent once.
