Realm vs third-party server
Realms outages show on Minecraft.net status. Third-party servers need their own Discord for host crashes.
How to fix step by step
- 1Check Minecraft and Xbox Live status.
- 2Rejoin after 60 seconds — host may have crashed.
- 3Lower render distance and simulation distance.
- 4Disable VPN.
- 5Update Minecraft launcher.
- 6Ask realm owner to backup and restart the world if repeats.
How CONNECTION-LOST differs from related codes
- Error FAILED-TO-CONNECT: Minecraft Java or Bedrock could not reach the multiplayer server. (server or client)
- Error CONNECTION-RESET: The multiplayer server closed the TCP connection before join completed. (server or client)
- Error OUTDATED-SERVER: Your Minecraft client version does not match the multiplayer server version. (usually client-side)
