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!

    I’ll double check this, but my router is enterprise grade so I don’t think I would hit any NAT limitations.

    Also, as mentioned in my other response, this isn’t affecting any other nodes on my network except the server running Qbit and Jackett.

    I have another Ubuntu VM on the same host that works fine when this one is failing.

    Thanks so much for the response!
