My last anyconnect contact link "devnetsandbox-emea-gwy.cisco.com:20207" requests my username/password.
The latest anyconnect contact link "devnetsandbox-emea-gwy.cisco.com:20210" doesn't ask for username/password.
I haven't received an email at my address but get this value from the devsandbox output command window.
I have uninstalled and reinstalled the app.
I have reloaded the iMac.
The next step was to hit the CLI on the Mac, uninstall the app, then remove the /opt/cisco directory.
Reinstall the app and try again.
This worked, when I restarted the sandbox connection I did NOT start anyconnect. I let the sandbox come up all the way and show me the new anyconnect information, devnetsandbox-usw1-reservation.cisco.com:20301.
At this time I restarted the anyconnect app and this time it displayed the group plus the username/password log in request. I entered the information that was displayed in the sandbox output window and got connected.
Unfortunately by this time it appears that all the reservations are used and I can't get another one, hahahaha.
At least I got it working.
