When our users try to connect to any app hosted on one specific host via the web gateway it times out and gives error 1030. We don't see an embryonic connection in the console.
All apps work internally to that server, it only throws the error when accessing it via the Secure gateway. Accessing the same app via a different host works just fine.
DNS to and from the Secure gateway from the host resolves fine, all servers including the gateway are on the same subnet, no windows firewall or otherwise is in place between them. IP's are pingable.
Which ports need to be answering on the server?
What else could be the cause?
