Quick answer

Start by separating service availability, version mismatch, world settings and local network problems. Changing several settings at once makes the real cause harder to identify.

What is confirmed

  • Crossplay depends on joining an appropriate world.
  • World invite codes identify a session; they are not account rewards.
  • Dedicated servers use a separate server tool.
  • Updates can create temporary version mismatches between clients and servers.
  1. Confirm every player has completed the latest update.
  2. Restart the game and verify the same world or invite code.
  3. Check crossplay and privacy settings on the relevant platform.
  4. For a dedicated server, inspect its current log and confirm it finished starting.
  5. Test with one client before changing router or firewall rules.

What this guide does not assume

  • Do not disable security software permanently.
  • Do not delete saves as an early troubleshooting step.
  • Back up configuration and world data before reinstalling a server.
