Steps to reproduce

It can't be reproduced after I restarted the application. However, my last actions were:

1. Started downloading a file from a magnet
2. Clicked trackers on the bottom, and added trackers from https://trackerslist.com/best.txt
3. Clicked right context menu, and clicked reannounce to all tracks

Additional context

I used a HTTP Proxy

• for torrents
• for hostname lookups

But not for peer connections

Log(s) & preferences file(s)

No errors found in logs but only got

qbittorrent.log:(N) 2023-06-13T**:**:** - Added tracker to torrent. Torrent: "**. Tracker: "udp://**1337/announce"
