Unable to Reserve DNACLab

[Anand G]

Hi,

Whenever I try to reserve a lab from the site "https://developer.cisco.com/catalyst-center/" for the options "Reservable Sandbox" or "Always-on Sandbox", it is throwing the below errors.

400 Bad Request

Request Header Or Cookie Too Large

nginx

How shall I proceed further?

@Anand G open the sandbox page in a private or incognito browser, this will redirect you to the main sandbox catalog page - this works ok.
