Episode 146 — Troubleshooting Certificates — Expired, Revoked, or Misconfigured

Certified - CompTIA Cloud+ Audio Course

In this episode, we examine common certificate-related issues and how they impact cloud services. Expired certificates can cause service outages, prevent secure connections, and disrupt authentication flows. Revoked certificates, often invalidated due to compromise, require immediate replacement to maintain trust. Misconfigured certificates—such as incorrect key usage, missing intermediate certificates, or mismatched domain names—can trigger browser warnings or block application traffic.

We also discuss troubleshooting steps including checking certificate chains, verifying expiration dates, reviewing Certificate Revocation Lists (CRLs), and testing configuration with validation tools. For the Cloud+ exam, knowing how to identify and resolve certificate issues is key to maintaining secure and reliable communication channels.
