Does anyone else run into this issue on Chrome, where after logging into https://devnetsandbox.cisco.com
with your CCO login, it returns this Request Header or Cookie Too Large HTTP 400 Bad Request error?
I can fix it every time by right-clicking > Inspect > Application > Clear site data... but I'm not sure it's supposed to work that way 🙂
It seems to be platform independent, Chrome on Windows and MacOS have the problem. Firefox on either does not.
Solved! Go to Solution.

This is an unfortunately known issue @bmcgahan. Clearing the cookies is the only solution. Is not a problem on the sandbox side, but rather on SSO across Cisco sites.

I guess a known issue is at least better than an unknown one, right?

@bmcgahan indeed, known are always better than unknowns. I'm thinking we need here on the community and in our sites some sort of FAQ for known issues. I will see how to make it happen.
