Unknown username and password for docker SSH

[Usalabs]

I can use Portainer with no problems but parts of Portainer don't work, so I'm trying dockstation, but when I add -H tcp://0.0.0.0:2375 to my docker service file, restarted the daemon and restarted docker, then in the dockstation connections manager I select SSH as the connection, then enter the IP address of my docker server (which is a LAN IP), then the docker SSH port 2375, then select auth type as plain, then? Now this is where I have no idea what the docker SSH username and password is, as my server host's SSH username and password work fine when using puTTY, but those are not the docker SSH credentials, so what would the docker SSH username and password be?

I also get in the SSH log for dockstation an error, connection error ETIMEDOUT connecting to......, I even tried increasing the docker MTU in the docker.service file, but made no difference. So it looks like the only UI that works is Portainer.

SSH is only used to tunnel to a remote Server and you use your SSH username and password for this. DockStation will find the running containers automatically.

That's the problem though, I tried using my SSH username and password that I use to remote access via PuTTY, but dockstation still pops up the request for a username and password, I even tried the docker SSH port 2375 and even the regular port 22, but nothing works, I even tried using certificates created on the host using ssh-keygen, then copying the private and public keys files to the client and adding the certificate path in dockstation, but still no go, when I use certificates, the connection just hangs, no password request, no anything.
