We have policy manager access enabled on our defined listen port of 9443 as seen here:
However when we attempt to connect to policy manager on port 9443 we receive an error indicating "Cannot connect to the gateway xxxxx:9443"
Executing a netstat command on the gateway shows that port 9443 is up and listening for incoming connection requests.
However when we execute the following from the host which we are launching policy manager from we can see that a connection could not be established:
curl -v telnet://GatewayHostname:9443
It would appear there is a firewall in place which is preventing the host where policy manager is being run on from communicating to the gateway over the desired port.
Working with our internal network team and we opened up port 9443. We could then successfully use policy manager and connect to port 9443 on the gateway.
