WiFi on demand stopped working?

I’ve been purchasing an access pass monthly with no issues. This month, my phone recognizes the hotspot but when I connect it doesn’t redirect me to the on demand page to buy my pass. So I manually enter it in on the browser and it doesn’t recognize that I’m on an xfinity WiFi network because it won’t let me activate the pass I’ve already purchased. What is going on?

I’ve tried going to and using different hotspots, same exact issue. I’ve tried clearing the cookies from my phone, forgetting the network and retrying. Absolutely nothing helps on any hotspot I try it on! Please help
