Left 4 Dead 2

Left 4 Dead 2 server not showing up or unable to connect

Use Left 4 Dead 2 and the server’s assigned game address. A lobby can choose a different dedicated server, so a direct connection is useful when checking whether this particular instance works.

If joining fails

Check Default Map and the complete custom campaign package if players fail during loading. Test c1m1_hotel as a stock starting point to separate custom content from the connection itself.

  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.
