Hello,
You know what it might be, I installed the server on a WIndows server 2012, I already disabled the firewall, I already checked with the hosting, but only the API port is open, port 5400 I can't access from outside
The API port 5401 works, now if I change the server port to 5401, and from the API 5402, port 5401 is closed, it seems that the server cannot open its own port, and only the API port
