Unable to find a microphone for these people

yes the problem lay with the Sky hub nothing to do with the Xbox.

I removed all port forwarding rules set up previously that did work initially.

These ports still show as closed via a port checker tool but the Xbox works with no manual setup.strange!

I’ve got the same problem. Tried everything, and support was as useful as a chocolate teapot. I’ve watched all the vids on YouTube done all the hard resets and unplugging. Support just suggests a factory reset. Which I can’t be **** to do.

Any luck with a solution??

We have had the same issue for the last 24 hours also

Tried everything that many forums suggest - and still no joy
