When you first launch WeVPN go to the menu icon -- three dotted icon on top right -- select Settings then proceed to the following!
NOTE: In Network be sure to keep CUSTOM DNS to be OFF! And if you set split tunnel be sure to keep the qBittorrent client in the tunnel!
In the settings page go to Privacy and set the killswitch to either Auto or Always, I would also suggest setting Auto-Reconnect to be CHECKED! Why? If you drop a connection this setting will automatically reconnect the VPN instead of leaving it disconnected.
After this go to Protocol and use WireGuard if you can not connect on WireGuard use Automatic or try IKEv2 and OpenVPN manually.
Now in qBittorrent click the Gear icon or go to Tools then to Options and or press CTRL+O at the same time.
In Settings go to Connection and in there set Enabled Protocol to TCP, Uncheck Use UpnP / NAT-PMP, and Uncheck Use different port on each startup.
Now go to Bittorrent and Uncheck, Enable DHT, Enable PeX, Enable Local Peer Discovery, set Encryption mode to Require Encryption*, and* Check Anonymous Mode.
Now go to Advanced and set the Network Interface to WeVPNs. If you do not know what this is go into Network & Internet Settings and then into Change Adapter Options. The WeVPN interface is the one using the TAP Adapter or the WireGuard tunnel -- if on WireGuard it is already named as such in Windows by default.
After you figure out the adapter either RENAME it or SET it to that Adapter in qBittorrent!
