Hello, the server startup time depends heavily on your hardware and map size.
Maybe you can change something there.
This means that the connection to the server that was supposed to receive the map file was actively disconnected by the target server.
The file is too large or the upload is taking too long.
The connection is unstable or slow.
The server intended to receive the map file is unavailable or is blocking the connection.
A firewall, proxy, or security software could be interrupting the connection.
