The issue was compounded by expired or unused certificates that remained in the certificate store within Aria Operations, which had not been cleaned up.
Note: This is a known issue and has been addressed in VCF 9.0.
Please follow the workaround mentioned below

2. Remove Expired/Unused Certificates

Use the search bar to locate the vCenter adapter certificate identified earlier
Select the certificate and click Delete
3. Validate Adapter Connection
Re-test the vCenter adapter connection using steps in the KB
4. Perform Configuration Drift Check
