I teste "private Server and gateway", "private server".
It is possible do a reset to the configs?
"Private" server mode blocks all access from the Internet to your server. Your server cannot be seen by users on the Internet.
I suggest you Reconfigure your server to either Gateway & Server mode or server only mode, depending on your requirements.
Log in as admin, and select Configure this server, then select the required mode (and not a private mode).
