Hello,
Tested RDP and it seems to be working, however the username should not be the PC name displayed in the Remote Desktop configuration in Windows. It should be your account name. By default Windows names the PC after the administrator account name, so if the PC name is Peter-PC, then the account name will most likely be Peter.
Password used should also be the password created on Windows (not PIN or any other authentification method).
Let me know if this helps!
Best regards,
