Sftp is not respecting the port

[C0D3-M4513R]

I am trying to configure sftp access to a dedicaded server.
What I have noticed is that the sftp dialogue (even if it submits when I am done) doesn't respect the listed port.

I am trying to change the port to 2022, because I am using pterodactyl and #204 / #292 .

I however noticed that there are only ssh connection attempts to the port 22 by my ip, but not to port 2022.
The file picker only ever starts validating, but never really finishes (it just times out after a seemingly too long time).
In the stdout there is also not really any useful information.

As it stands, I can not use this software at all to manage my server.
