## Symptoms

- Outbound HTTPS Inspection of self-signed certificate websites may fail with various errors:  

- CRL Validations failure logs  
- Self-Signed certificate failure logs  
- HTTPS Validation failure logs or Reject logs

## Cause

By design, when HTTPS Inspection is enabled, CRL Validation is also enabled by default.

Therefore, inspecting traffic towards a website that owns a self-signed certificate (without a Root-CA / Sub-Root-CA) will fail because of the CRL Validation feature, which validates expiry, all certificate chains and their order, trust state, and more.
