When attempting to deploy probes to a hub with a local ADE and Distsrv we are seeing the following error
Caused by: java.net.UnknownHostException: samplehostname.com: samplehostname.com: No address associated with hostname
... 22 more
The hosts file is improperly setup. The ADE is doing a lookup and not able to find itself and thus, unable to deploy to that system.
To resolve this add the samplehostname.com to the top of the /etc/host.
This is assuming the FQDN is samplehostname.com and the local ip address you wish to communicate with is 192.168.0.10
Once done, simply cold start the automated deployment engine probe and try to redeploy via Admin Console.
The issue should be resolved.
