Trying to use the Firepower Management Center Rest API Sandbox, it's listed in the catalog page:
https://developer.cisco.com/docs/sandbox/#!security/security-sandbox-highlights
But when I click on the Try it out link, it opens a new window to:
https://devnetsandbox.cisco.com/RM/Topology
With the "Sandbox Lab not found" message at the top.
Any idea when this will be made available again?
