qBittorrent stopped working around the time when i reconfigured after the core-updates-frozen merge.
the new behavior is that it can connect to trackers, it gets the peer list, but when i switch to the peer list tab of a specific torrent, what i see is that peers keeps showing up and then immediately disappear.
the number of DHT connections also remain at zero.
on my router i can see UPNP opening the relevant tcp and udp ports, and there's no firewall on the computer itself.
nothing else seems to have changed in the environment, and qBittorrent on a windows machine works on the same network.
