Monitoring and connection problems
Interpreting activity, missing data and rejected connections.
What monitoring shows
Monitoring includes active connections, recent joins, departures, rejections and available Minecraft version information.
online counts active proxy connections. It does not prove that every player has finished loading a world. null means no fresh data source, not zero players.
A player cannot join
- Check the domain and port against DNS instructions.
- Check backend reachability and how it accepts connections from Lumin.
- Find the event at the time of the attempt, including the game version.
- Use the monitoring report action for a false rejection.
Operator diagnostics are not part of the public documentation or the full customer monitoring response.
