Hello wyehya,

I think....Cisco has been  switcing to a new sandbox platform and it will take a few days  to reach a steady state.

Hello! I have tried to enter the sandbox page https://devnetsandbox.cisco.com/DevNet but it gives me an error.

I have Chrome Version 120, I have used another browser, I can access it.

I have used incognito mode in Chrome and I can enter the sandbox page, the same with another browser, so clearing cache and cookies would solve this problem.

I have the message:

400 Bad Request
Request Header Or Cookie Too Large
nginx

Happy Holidays!
