Firewall Settings

If you’re hosting a Garry’s Mod server on a computer with a firewall, you may need to allow incoming connections on the required ports. Check your firewall settings to make sure the necessary ports are open.

Server Crashes

If your Garry’s Mod server crashes, it may be due to a plugin or mod that’s causing issues. Try disabling any plugins or mods you’ve installed to see if that fixes the problem.
