It seems to be Cisco's problem. Port 443 is not reachable at aggregator.cisco.com from the ESAs or even in a web browser. I checked the status of services (https://urgentnotices.statuspage.io/) and nothing has been posted yet.

I looked at as well. nothing posted about this issue. I am afraid the problem would stems from my side.

I have reported this to TAC.

Connections are successful now.

are you sure? I get the same message every 30 minutes

Well, I was able to connect, but the connection is down again and I continue to receive the alerts from our ESAs, as well. TAC has not responded and the status page [1] still lists all services as operational.

TAC has responsed to our case that it is/was a global issue.
