Connection verification failed

Code

MULTIPLAYER/CONNECTION_VERIFICATION_FAILED

What it means

The server could not confirm that the player’s connection is valid for the target realm/room, so it rejects the join.

When it happens

  • A player joins a realm/room but verification fails (realm not verified, invalid session, etc.).

Typical scenarios:

  • Room initialization failed on the server (terrain params missing, storage load failed)
  • Player/session metadata is invalid
  • Realm is not in a verified/ready state

How to handle

  • Treat as non-retryable unless you know the server just recovered.
  • Log meta.realmId, meta.socketId, and meta.via.
