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.
