If joining fails
Read Console for a version, mod or map error before changing the port. The installed launcher uses the server’s assigned memory allowance for Java, so arbitrary JVM values are not a solution to an incompatible client.
- 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.
