Use the complete server address exactly as supplied, including its protocol, any port and any required path. Do not add a guessed ending or remove a port to make it look cleaner. A correct username cannot compensate for an incorrect server address.
Keep the protocol attached
The beginning of an address, such as https://, tells the player how to connect. Some forms add a protocol automatically and others do not. Read the example shown beside the field so that you neither omit it nor accidentally enter it twice.
Treat ports and paths as meaningful
A colon followed by numbers can identify a specific service port. A path after the domain can also be significant. Copying only the domain from a longer account message may point the player at a website instead of its account endpoint.
Correct transcription errors methodically
Compare the first characters, domain spelling and final characters against the original message. Remove a trailing space introduced by a clipboard, but do not rewrite the address based on a web search. If the supplied address fails consistently, ask the service to confirm that exact endpoint.
