@QGB I guess you forgot to add a host key to the server.

Replace the nil param to ssh.HostKeyFile("/path/to/key") in the following function call:

log.Fatal(ssh.ListenAndServe(":2222", nil,
                ssh.PasswordAuth(func(ctx ssh.Context, pass string) bool {
                        return pass == "123123"
                }),
        ))

I don't think this is a bug so could you (or anyone) please close this issue?
