[HELP] Gmod listen server stuck as 'Garrys Mod"

Whatever I do, it is always stuck as that…
I tried all the solutions other people said on a google search but it didn’t work, help please?
(It’s a listen server, not dedicated. I run it directly from Gmod)

You said you tried all the solutions, but didn’t mention what any of those were. You at least tried changing the “Server Name” field, right?
