Hi @tarek21,

Here are some tips for you if port forwarding doesn't work:
    1. Make sure the server is accessible from the internal network.
    2. Make sure your router obtains the public WAN IP address, if your WAN IP is not a public one, port forwarding will not work. (CGNAT address is also private IP address that ranges from 100.64.0.0 to 100.127.255.255.)
    3. Check the firewall settings of your server, make sure it allows traffic from the outside Internet.
