Assuming that the server is on your home network and that the external IP address is the ISP-assigned address given your router ...

If you turn off wifi then your device will be talking to your carrier and coming at your router from outside. The router will pass the communication to your internal server, and all is well.

If you are on wifi, then your device will talk to your router but from the wrong side of the router. In order to work, the router must "loop back" the connection, in effect pretending that it came in from outside your network. Most routers are not capable of doing this, and the ones that are often require special setup.

The "normal" way of handing this problem is to have a DNS server inside your network that will hand out the internal IP address for your server to devices inside your network. The outside DNS server will provide the external address.

To avoid this problem, CC provides two network settings for the content server connection. You would put the external IP address in one of them (or a URL or something), and the internal IP address in the other.
