We are unable to access the secondary hub. Getting the below error...But we are able to telnet to the primary and tunnel hubs without any issue. Recycle of robot/hub had no effect, restart no effect. The secondary hub normally connects to the Tunnel Server (Linux).
hub log showed:

hub was pingable
telnet to the robot port 48000 was successful but not the hub at 48002
But when trying to resolve it, we get non-existent domain and we noted that the other Secondary hubs were 100% resolvable in AWS.
*** awsxxxxxxx.dxxx.com can't find xxxxxxxHUB: Non-existent domain
We checked 3 other Secondary hubs in AWS and they CAN be resolved with no issue.
