Xbox One 'UPnP Not Successful' error explained

Ports are digital channels for your router, used for sorting incoming and outgoing internet traffic. Universal Plug and Play (UPnP) essentially allows applications to forward ports automatically, avoiding the hassle of manual "port forwarding." 

Although they often achieve the same end result, UPnP allows the console to seamlessly request a port, rather than requiring specific port numbers to be entered manually. And for many, it's a simple flick of a switch.

However, if issues with UPnP surface, your Xbox One can display a "UPnP not successful" error in its network settings. This message indicates issues with utilizing UPnP and failing to automatically forward the correct ports. As a result, connectivity issues can be experienced with Xbox Live.
