Environment

VMware Aria Operations 8.18.x

Cause

Connectivity between the configured endpoint and Aria Operations has failed due to an expired or renewed endpoint certificate, or invalid credentials.

Resolution

1. Verify that the certificate on the endpoint is not expired before proceeding. Renew certificate on endpoint if required, by following vendor documentation for replacing certificate on endpoint
2. Follow procedure in KB article How to renew an adapter certificate or clear the Expired Certificates banner in Aria Operations to import new certificate from endpoint, ensuring that you import new certificate from endpoint before deleting expired certificate
