Windows Garrysmod Startup Error

Having a issue when recieving this when starting my server on my dedicated server
“Warning! Singleplayer mode not available on dedicated server.” Any ideas how I can fix this?


Commandline? Installed trough hldsupdatetool?

Maxplayers needs to be higher then 1.

Changing max players worked but cannot see it online the server is not behind a firewall so I dont know whats up at the moment.

Well, that can have a lot of reasons. Take a look at routers portforwarding.
However, I doubt that’s complete. I think the masterserver is using another port for communication.
