Counter-Strike: Source server not showing up or unable to connect

If joining fails

If direct connection works but the browser listing is absent, inspect the Steam token and registration messages. If a custom map fails, compare the map and required assets before changing network settings.

1. Open Console and wait for the game or world to finish loading. Save the first error if startup stops.
2. Use the joining method above with one client on the matching game version and required content.
3. If entry is rejected, compare the exact error with the password, edition, map or authentication checks above. Keep the working save while testing.
