Denied when logging into Xfinity hotspots away from home

I have Xfinity X1 and cant log in to Xfinity hot spots away from home. It tells me that access has been denied. Ive called comcast with no recognition of the problem let alone a resolution. They have no idea what is wrong or how to fix it. Please advise. I am unable to send a screen shot on here. This is the message I recieve every time,
"Access temporarily denied on this device"
