The name server_id is ever so slightly ambiguous, and it could be easier for a new user to see server_key which matches the response from https://parsecgaming.com/server-key
Additional validation could be added to ensure that the User does not paste additional unwanted information (such as :server_key=*********************).
Another nice to have feature would be to support pasting into this field, as I was only able to use the context-menu to paste.
