We have published the Policy Manager to our DMZ network. However the Server Security can't connect it. There is a firewall between the server and the Policy Manager but it is not showing any denied connections on the firewall log. Both http and tcp/8080 are open for communication.
The error is:
Connecting to http://zzz.yyy.xx (no BW proxy, no HTTP proxy)...
Update check failed. There was an error connecting http://zzz.yyy.xx (Connection refused)
