Connectivity failures commonly result from an incorrect endpoint, protocol mismatch, blocked route, untrusted certificate, or invalid credentials.
Checks
- Verify the host, port, protocol, and path supplied for the deployment.
- Confirm DNS resolution and outbound network access from the actual application or collector environment.
- Match the exporter protocol to the receiving endpoint.
- Inspect certificate validity, hostname matching, trust chain, and system time.
- Confirm that credentials belong to the selected client and have not expired or been revoked.
- Review sanitized error text for timeout, connection refused, handshake, certificate, unauthorized, or forbidden results.
Do not disable certificate verification as a production workaround. Install the approved trust chain or correct the endpoint name. Rotate exposed credentials immediately and never include secret values in screenshots or support bundles.
