# requests.exceptions.SSLError: HTTPSConnectionPool(host='revoked.example.com', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate revoked')))

- **ID:** `python/requests-connectionerror-ssl-certificate-verify-failed-crl`
- **Domain:** python
- **Category:** network_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The server's SSL certificate has been revoked by the issuing CA.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.x | active | — | — |

## Workarounds

1. **Contact the server administrator to obtain a new certificate** (95% success)
   ```
   The certificate must be re-issued by the CA.
   ```
2. **Use a different endpoint with a valid certificate** (80% success)
   ```
   requests.get('https://valid-alternative.example.com')
   ```

## Dead Ends

- **Setting verify=False to bypass** — Bypasses security but does not fix the revoked certificate; insecure. (60% fail)
- **Using a different SSL library** — The revocation status is checked by the CA, not the library. (90% fail)
