400 Bad request Your browser sent an invalid request.

Post by worahm »

When trying to access my xfinity email I receive the following message..."400 Bad request. Your browser sent an invalid request."

There is no problem connecting using Internet Explorer. I am running Windows 7,64 bit computer.

This happened intermittently for the first time about a week ago. Now it happens all the time.

Would appreciate any help. Bill
