Anyconnect from Cisco is no longer free software;! Try/Use Open Connect or whatever comes with Windows OS, aka other VPN software.

this is likely issue on their side (server); However, DevNet SandBox support stuff maybe out last week; We had Easter week! Hopefully, they are back today!

Try later today! Let us know.

Just a quick update on the Cisco Modeling Labs (CML) sandbox — it’s now back in the catalog and fully operational.

We recently completed a round of maintenance to improve stability and performance. Everything is now up and running smoothly, and you should be able to access the sandbox without issues.

Thanks for your patience during the maintenance window, and feel free to reach out if you run into any problems or have feedback to share!
