Getting Retrospect Backup Application through Firewall

[Earthling]

Hello,

Still learning FortiGate.  

Experiencing difficulty getting access through firewall for Retrospect backup software.

Retrospect is telling us, 'Host Not Found. Or Network Unavailable' when we try connecting to MS Azure or AWS.

Retrospect communicates through port 497. And we opened that port.  Still, no joy.

Any suggestions as to what is blocking our access?

And solution?

Thanks in advance!

what is the policy that you have created?

when you test the connection what are the logs that appear?
