Testing and Troubleshooting SSL/TLS
Testing SSL/TLS Configuration
You can use tools like OpenSSL to test your SSL/TLS configuration:
openssl s_client -connect localhost:9200 -CAfile /path/to/elastic-stack-ca.crt
Common Issues and Troubleshooting
Issue: Certificate Verification Failed
Ensure that the certificate paths are correct and that the certificates are valid. Use OpenSSL to check the certificate:
openssl x509 -in /path/to/elastic-stack-ca.crt -text -noout
Issue: Elasticsearch Fails to Start
Check Elasticsearch logs for error messages related to SSL configuration. Common issues include incorrect paths to certificate files or missing configuration settings.
Issue: Curl Command Fails with SSL Error
Ensure you are using the correct CA certificate and that the Elasticsearch node is accessible over HTTPS.
