Can’t connect to xfinitywifi network

Hi,
Normally when I’m visiting my parents (who aren’t tech people and don’t have their own WiFi network), I usually can always connect to the xfinitywifi network without issue, but I noticed when I arrived here tonight, that there is an exclamation point next to the network name and when I connect, it says “no internet, open.

To clarify, this is NOT an issue with my networks at home. Did Xfinity change the way that connectivity to the “xfinitywifi” network works?

Thanks!
