SL requests are being blocked

Hi Gustavo

From which version to which version did you move?

Do you mean Web Filter is affected? Do you see any error message or security/traffic log?

Hello! 

Did you upgrade from v7.4.5 or v7.2.11? Please see this article and let me know if this aligns with what you're seeing: https://community.fortinet.com/t5/FortiGate/Troubleshooting-Tip-How-to-fix-SSL-connection-is-blocked-due-to/ta-p/362052

The fix is a CLI change to your SSL/SSH Security Profile. However this change cannot be made to the default SSL/SSH profile if you are using it. If you're using the default, clone it and just make the set cert-probe-failure allow change then apply it to your policies.
