I reserved the Collaboration 11.0 sandbox for a 3 hour period. Shortly after the 2 hour mark the RDP session lost connection. Attempts to reach the other administrative screens failed. I attempted to disconnect and reconnect to the VPN. I was unable to for about 10 minutes. I'm reconnected to the VPN but attempts to load the CUCM Publisher administration page via the link at https://devnetsandboxlabs.cisco.com/index.html brings me to an error page with the below message:
Unable to connect to server 10.10.20.1 .
The server may not exist, or access to it may not be allowed.
Attempts to connect to the RDP fail to connect.
Please help and thank you
