Xbox One: UPnP not successful - what you can do

The error "UPnp not successful" appears on the Xbox One when the console cannot automatically unlock the ports in the router. This circumstance sometimes leads to problems with online games, as they can't connect to the game server or voice chat doesn't work.

How to fix the "UPnP not successful" error on Xbox One

UPnP stands for "Universal Plug and Play". This feature allows devices that are on your network to customize port sharing themselves. This has the advantage that you don't have to do this manually, as was the case in the past. However, the setting can also be used by hackers to gain access. So if you don't have any problems within your online games, leave UPnP disabled. If you still need to enable UPnP, then you should only do so for the XBox One.

1. Go into the settings of your router. If you have a FritzBox, you must enter the address "fritz.box" in a browser of your choice.
2. Search for the Xbox One in the "Home Network Overview" or the equivalent and click "Edit".
3. Erlauben Sie hier die selbstständige Portfreigabe.
4. Starten Sie danach den Router und auch die Xbox One neu.
5. Nach dem Neustart sollte der Fehler verschwunden sein und alle Online Gaming Funktionen wieder funktionieren.
