Ubuntu server can't connect to some sites when qbittorrent is running
Hey all, ran into a weird issue with my Ubuntu server running qbittorrent-nox I can't seem to figure out.
When Qbittorrent is running, I can't load some sites. How I discovered this was Jackett was failing tests to my trackers. Sometimes all trackers would fail, other times only a couple would.
From the server I ran a curl to the tracker URLs and confirmed they were not loading.
Pcap shows the TLS hello go out, but no response from the server.
Once I kill the qbittorrent process, everything works.
Wondering if anyone has any ideas or has seen this issue before.
Things I've tried:
- Disabled ipv6
- Changed Qbit UI port
- Paused Torrents
- re-installed openssl
- rebooted about 150 times and counting
Qbit version is 4.5.5 Ubuntu 22.04.3 headless running on Esxi
Appreciate any ideas!
Edit: So after much frustration and some other weird things, restored to a previous snapshot and the issue seems to have resolved. Appreciate all the troubleshooting ideas and responses!
From your description I would gues that the affected trackers have some rate or connection limits, and your qbittorrent announces are exceeding them. try setting a higher announce interval, like 1+ hours
Anonamouse just announced that they're likely to ban some client/version pairs precisely because of announce floods. Thing is, does the problem clear up instantly when the client is killed, or does it take time? The latter would indicate a server side van expiring, the former some issue on the client side.
The issue would resolve almost immediately after killing Qbit.
