[Solved] cant join the server

[Santacake]

I had the same problem on a different server with the same error message. All I did check my maps folder in "C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\maps" and deleted the map with the same name XD . The error means literally what it says so you might also want to look in your addons folder in the game and see if you downloaded the map from there, and disable it. Then re-extract the map from the server.
