Workaround 1:
Recommended enabling bi-directional communication on TCP port 443 from the vCenter instances to all nodes within the Aria Operations for Logs environment.

1. Open SSH session as root to Aria Operations for Logs Primary node                                                        
2. Run either of these following commands to test connectivity on port 443  
   

      curl -v telnet://<vCenter_ip_address/FQDN>:443
      nc -vz <vCenter FQDN> 443

3. Repeat for each Aria Operations for Logs node as necessary.
