Site only works with web filter disabled

I can only access a specific website when I disable the web filter.

 

The Fortigate 40F firewall doesn't display any message informing the blocked category. The website isn't placed in any category.

 

When I disable the web filter, I access it normally.

 

I've already placed the website in the Static URL filter, including Exempt, Block, Allow, and Monitor... but nothing happens. It doesn't block or allow.

 

I've also disabled the Fortiguard Category Basel filter, and nothing happens.

Hello @zeeorlando ,

 

It seems your problem is not related to the web filter. 

 

You can follow that document for fixing ssl inspection issue.

Hello @zeeorlando ,

 

Do you have a valid WebFilter license? 

 

Also, can your FortiGate reach FortiGuard IP addresses?

Yes, I have a license, and FortiGuard is working perfectly...

Blocks websites that fall into the categories listed in the FortiGuard Category Based Filter.

Hello @zeeorlando ,

 

Can you also share web filter logs with us?

yeah the log states it was blocked by certificate inspection due to ssl annomaly (because it was unable to fetch the servers certificate)
