While an internet connection unlocks the best of Xbox One, networking is paired with countless issues to encounter. If you're experiencing Xbox One's "UPnP not successful" error in your network settings, here's how to fix it and get back to gaming.

Everything you should know about Xbox One networking

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.

  • I generally keep UPnP turned off on my routers for security reasons. I've not noticed any problems with my Xbox One X (or any other devices), that I know are because of that. I did have problems with LAN play on Minecraft recently and Realms lists being blank, which may have been related to UPnP, but it seemed to start working again with the latest Minecraft update, so maybe that had nothing to do with my network settings after all (not sure). What would the symptoms be of a problem that was caused by disabling UPnP? Does anyone need it?
