qBittorrent "Invalid Username or Password. Server response: Fails." [Accepted]

[Fusor]

Good day!
I bought a F8 SSD Plus NAS recently and I've installed the qBittorrent client from the App center, howeveer, I can't log into it. I write my name and password (more like BitWarden writes them for me), the ones that I log into TOS in the first place and I get the

Invalid Username or Password.
Server response: Fails.

message. I've never launched it before that on the NAS and never set anything as username or password for it. The problem is from launch number 1 of the fresh installed qBittorrent. Any suggestions are welcome.

The default username is admin, and the default password is adminadmin, which you can see in the introduction of qBittorrent in the Application Center.
