Regenerate Root CA Certificate using Admin UI
It is recommended to regenerate the trusted Root CA Certificate file using Admin UI of Web Safety. To do that open UI / Squid Proxy / HTTPS (SSL) / Root Certificate . Click on the Generate New Certificate button, fill in all fields as required, scroll down and click the Generate Certificate button.
If you had SSL inspection activated with a different Root CA certificate before, then some generated SSL certificates may have been stored by Squid on disk to speed up SSL filtering. Web UI correctly removes these cached certificates upon generation of a new certificate. No action is required from you.
