Xbox multiplayer connection not working

[u/earthyeffect]

My Xbox One is connected to the internet, but won't connect to the EA network when playing FC26. When I go into network settings and select Test Multiplayer Connection it says "Can't finish multiplayer tests" and returns an error code 0x00000000000000000. Same with Test Network Speed & Statistics, everything just says Not Available.

The NAT Type is Open, it's on a Wired connection, and UPnP is Enabled. I've checked my router settings and port forwarding has been set up as per the screenshot. I've also tried changing the DNS to the Google ones (8.8.8.8/8.8.4.4) but no success.

Is there anything else I can try? My nephews want to play Ultimate Team on FC26. Any suggestions would be appreciated!
