Catalyst Center Always-On

walidgaber93 — Sat, 29 Nov 2025 10:52:37 GMT

Hello Team,

I'm trying to gain access to the Catalyst Center Sandbox.

As per the set up instructions below.

host: https://sandboxdnac2.cisco.com

username: devnetuser

password: Cisco123!

status: OK

When I add this link in the vpn it's showing that alert,

when i am opening this link in the browser showing not found,

Am i doing it wrong? and what is the correct steps?

I think u skipped 1st step; VPN connection to sandbox via email, You should get email with link to copy into VPN, then use host /name/ pass listed above

No, this is the first time i face that, i have another user in the laptop that i use for work and i use Cisco Anyconnect VPN and it's working normally,

Also tried Windows built-in VPN and showing error.

@walidgaber93 No vpn needed here, add the url to your browser and dnac ui will open, then enter your username and password you have above, and you are in. This sandbox is read only, so you can’t make any changes.

The only one I see in service is this one

The other I think was removed months ago. That said, I can’t open this page and the sandbox looks down right now ( the devnet team will need to advise here). You can the reservation based on, which does need a vpn.
