Hi Gopi,
1) What error message do you see in vSphere UI? It's possible this is unrelated since the registration would either succeed or not succeed. In the case of not succeeding, there wouldn't be any messages in UI (since it was unsuccessful). Can you confirm that your vCenter Server can communicate over 443 to VEBA Appliance which is serving the plugin?
2) Did you enable debugging when you deployed (option at the very bottom of the OVA). You can look at /var/log/bootstrap-debug.log and see if there's any immediate errors, the setup script is design to stop upon first error
The VEBA team is also on VMware Code Slack Channel https://vmwarecode.slack.com/archives/CQLT9B5AA if you wish to join and we can debug
Downloaded and installed the latest appliance. Successfully integrated with vCenter.
But, when I go to VMware event broker plugin in vCenter, I get a pink bar with a red exclamation.
