Hello,
Recently bit defender is starting to block xbox gaming connectivity. In order to fix this I had to preform one of the steps that was provided in the comments in an older post linked below.
I also know this is an issue because my server connectivity said it was blocked and after disabling firewall or adding svchost to a complicit allow rule in the firewall policy, I was able to authenticate with xbox servers and join a friends private game.
Can this please get fixed?
