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!
