Error for xfinity websites - 400 Bad Request Request Header Or Cookie Too Large openresty/1.13.6.1

After installing new modem/router device for XFINITY xFI, I began receiving this error for some Comcast web pages (mostly Help pages).

Anyone else experience this?  I am using Chrome Version 62.0.3202.94 (Official Build) (64-bit)

Thanks for that info.  I cleared cache & cookies and did the flushdns command (ipconfig /flushdns), but links still giving problems.

Since the links that give me the problem are all on Comcast web pages (mostly help), I will wait and try again, as your lifewire site reccomends.

This is an example of what gives me the error, from this webpage:  https://internet.xfinity.com/help/articles/Checking-for-Internet-Outages
