Your Map Differs From The Servers Error

What is it and why does it happen?

The “Your map differs from the server” error is produced when a player tries to connect when they have a different map download that is under the same name as the map your server/the server you are trying to join is currently running.

Method - For the Player

  1. Navigate to your Steam directory.

    *For example C:\Program Files (x86)\Steam

  2. From there, navigate to steamapps/common/GarrysMod/garrysmod/maps.

  3. Proceed to remove any maps that have the same name as the map that the server you are trying to connect to is running.

  4. Navigate back to the garrysmod directory and enter the addons directory.

  5. Proceed to remove any maps that have the same name as the map that the server you are trying to connect to is running.

  6. Restart Garry’s Mod.

  7. Attempt to connect to the server.

If the issue persists:
  1. Unsubscribe from the Workshop Addon for the map on Steam.

  2. Navigate to your Steam directory.

    *For example C:\Program Files (x86)\Steam

  3. From there, navigate to steamapps/common/GarrysMod/garrysmod/downloads/server.

  4. Delete the contents of the folder.

    *Note: This removes all files you have installed from any server, as a result you will redownload everything upon joining a server.

  5. Reconnect to the server.

Method - For the Server Owner
