Common SSL-related errors

This article outlines the most common SSL issues that may occur during Constructor Proctor integration and provides additional troubleshooting guidelines.

Typical Errors

Possible SSL-related messages include:

  • "An unexpected error occurred"

  • "Connection is not secure"

  • "Error 500"

  • Reviews failing to send to the LMS due to certificate validation failure, e.g.:
    send review response: SOCKSHTTPSConnectionPool... caused by SSLError(WRONG_SIGNATURE_TYPE)

Root Causes

These errors often stem from:

  • Expired, invalid, or self-signed certificates

  • Incomplete certificate chains

  • Untrusted Certificate Authorities (CA)

  • Unsupported or weak signature algorithms

Additional SSL Troubleshooting

To ensure long-term stability and compliance, check that:

  • SSLv3 is disabled (prevents the POODLE attack).

  • RC4 cipher is not in use.

  • Forward secrecy (PFS) ciphers are supported where possible.

  • TLS 1.0 and TLS 1.1 are disabled (deprecated and insecure).
