Bad Message 431 when trying to activate

I am getting Bad Message 431 with reason

"reason: Request Header Fields Too Large"

when I try to activate my xfinity internet online. I have cleared my cache and tried in a new browser.

On my app, it is an endless loop of trying to sign in and the welcome page not progressing after I've correctly entered all of my information.
