Hello,

 When I click on the Xbox Network Login button, nothing happens. It worked earlier yesterday, but it does not today. I can access Xbox Live from a browser and I most certainly have an internet connection. I have uninstalled and reinstalled the game multiple times. Any ideas? Oh, I play on the PC and have the game via steam.

@ohboy  I was just experiencing this problem this morning, and I just got it working.  I had to explicitly sign out of the XBox GamePass PC client and sign back in again.

My guess is that somewhere between a couple days ago and today, my Microsoft-issued authentication token expired and wasn't successfully passing into Obsidian's environment (I'm making a few assumptions about how this works, full disclosure).  But once I did sign out (top-left menu where your player handle/avatar is > Sign Out) and then signed back in (client restart wasn't necessary), it fired right up!

Hope that helps.  Not sure what happened, but definitely seems like an expired token/cookie somewhere.
