I tried using qBitTorrent after doing a clean install of 20.04. When I ran a test search, it returned an error. I tried turning all permissions on and that made no difference. Since I still have a 19.10 install on another computer I confirmed qBitTorren works there using the regular install. I then tried the snap install. Same network issue as on 20.04. I added the qBitTorrent repository to apt and downloaded direct. That version works fine. (It also starts much more quickly and seems snappier. Pun intended, of course!)
As a work-around, instead of using the snap, direct install it from the developer. You can find information on that here: https://www.qbittorrent.org/download.php
Or, if you're a wee bit smarter, follow this suggestion: What was wrong with installing it from the repository by sudo apt-get install qbittorrent? – N0rbert Apr 30 at 8:07
This is an issue with the default permissions that the snap builder included. If you look at the qbittorrent log you can see it is having connection problems.
to find the name of the qbittorrent snap. In my case qbittorrent-arnatious
