vCenter accounts are in Warning state due to "Certificate Validation Failed" and "Unable to connect to VC" errors

Products

• VMware Aria Suite

Issue/Introduction

• Provide guidance or recommendations to address the "vCenter Collection" issue.
• vCenter integration is in Warning state and when we Edit the vCenter adapter and click on Validate Connection, we see one of the following error messages:
  • Wait for response of task 'Test connection' is timed out for collector 'vRealize Operations Manager Collector-Collector name'
  • Error trying to establish the connection.

Environment

VMware vRealize Operations 8.x

Aria Operations 8.x

Cause

• vCenter SSL Certificates were not available in Aria Operations.
• Port 443 is not open between all the Aria Operations nodes and the vCenter.

Resolution

• Ensure that Port 443 is enabled bi-directionally between Aria Operations and vCenter. (Test connectivity using curl -v telnet://<IP Address>:443 command)
• Change Collector node for vCenter to Replica or other Node and the Test Connection should be successful.
• When testing the connection accept any SSL Certificate that is offered.
