Cannot connect to xfinity wifi hotspots after 11.4.1 upgrade

I have an iphone 6S and my phone just recently updated (out of nowhere) to 11.4.1. Ever since the upgrade I can not connect to the xfinitywifi hotspots in the city. Everytime I click on the xfinity wifi, it just says "unable to connect" it does not allow me to login with my credentials. I have reset all network settings and it is still not allowing me to connect.

Please help!
