🔍 Common Issues & Solutions

  • Certificate Installation Errors

    • Verify the certificate file format (e.g., PEM, DER) matches your server requirements.
    • Check for typos in the certificate path or filename.
    • Use openssl to validate certificate integrity:
      openssl x509 -in /path/to/cert.pem -text -noout

  • Protocol Version Mismatch

    • Ensure your server supports TLS 1.2 or higher (e.g., TLSv1.3).
    • Update OpenSSL or server software if outdated.
    • Test with tools like SSL Labs for protocol compatibility.

  • Certificate Chain Incomplete

    • Include all intermediate certificates in the chain.
    • Use the /Documentation/en/Tools/SSL_Validation tool to check chain validity.
    • Example command to chain certificates:
      cat intermediate.crt > fullchain.pem
