"Your Xfinity Internet service is not active" upon login to a wifi hotspot using my credentials.

Just as the subject says. When I try to sign in to access an xfinitywifi hotspot, it jumps to a webpage that says "Your Xfinity account is not active." I have an xfinity account that I pay for and my home internet on my modem router works. How can I fix this issue so I can get access to use the xfinitywifi hotspot like I'm supposed to be able to?
