HP Device Manager - Communication Error between Master Repository and Gateways

[srehl89]

Hey Community,

I got some issues by configuring an Multi Tier architecture of HP Device Manager (Thinclient Management). 

The setup I have:

1 HP Device Manager (Gateway, Master Repository, Server and Agent) 

Multiple HP Device Manager Gateways in remote locations attached via Private WAN with firewall in the middle

When I installed everything, I wanted to Search for Gateways in my Master Server to get connection towards the remote Gateways.

However when I click Discover > Discover HPDM Gateway, there is an error showing for all of the Gateways --> Communication error..

For the machines, where I didn't installed the HPDM yet, there is another failure --> Gateway unconnected (which is expected)

Does anyone had same problems, or what was your procedure for this case?

* I checked the firewall ports already, they are not filtered (400xx Port range, 6x port range etc.)

* Is there any certificate which needs to be exchanged, if yes, how?

* I installed the latest Service Pack on them

Thank you very much 😉
