Catalyst Center Sandbox issue

imran.zahoor — Wed, 28 Jan 2026 07:49:36 GMT

I am getting this error in Cisco DevNet Sandbox: 'Maximum number of concurrent environments for this blueprint has been reached.' Is the DNA Center (Catalyst Center) sandbox still operational? I've been seeing this error for a couple of days now.

Thanks

Yes, the Cisco Catalyst Center (formerly DNA Center) sandbox is operational, but this error indicates that all available instances for that specific blueprint are currently reserved by other users on a first-come, first-served basis. The issue is likely due to high demand or limited capacity.
