After connecting to Cisco VPN with the provided credentials, I have launched the SSH panel in the DevBox of the IOS-XR Sandbox then I face the below error in accessing the remote URL
Iam able to access the routers and the devbox using putty with the port details. I have a general query, is it possible to upgrade the routers with a specific IOS-XR software image provided by the user. can upgrades and downgrades possible?
