If joining fails
A checksum rejection means the required content does not match. A missing-checksum startup error means the server itself lacks the required car data. Those are different failures; changing ports will fix neither.
- Open Console and wait for the game or world to finish loading. Save the first error if startup stops.
- Use the joining method above with one client on the matching game version and required content.
- If entry is rejected, compare the exact error with the password, edition, map or authentication checks above. Keep the working save while testing.
