I am not familiar with this problem but it seems like your ssh connection gets hijacked by a cisco device and not allowed to proceed.

Check if you have an IP address conflict between this server and a cisco device interface IP. Best bet is to take the message to the network admins and by their help sniff the traffic to figure out which device is stronarming you to buy a cisco ssh license key, looking at the mac addresses.

Richard,
You need to talk to your network folks and have the ssh port opened up from the firewall.

I guess the error messages is clear:

ssh access is not working anymore on the cisco device because the license key is missing.

If the user used to reach a server under that address this might reveal a networking/routing problem. Maybe it's a kind of NAT or policy routing activated and configured the wrong way.

Maybe just the IP address changed?

May 2 cents,
Armin
