Cannot Get Online

I’m forced to stay in Horizon Solo on Xbox One X.

I’ve tried other games to see if it’s an xbox service issue and they’ve connected perfectly fine. I have also ran the consoles Network Diagnostics and that too seems fine with an open NAT.

This is the long error it gives me, and yes I’m typing it out:

Unable to join session.
