Web Filter issues

[luccap07]

Hello everyone.
I am encountering difficulties with our FortiGate 200E device at the company.
We are utilizing the web filter to control content access, however, we are observing inconsistent blocking behavior.
Specifically, when Proxy mode is enabled, certain categories of content are not being blocked as expected, despite being configured to do so. Conversely, when switching to Flow mode, the device is over-blocking content and miscategorizing websites. For instance, OneDrive is being classified as an abortion site, and YouTube is categorized as unknown.
I have already attempted to resolve this issue by updating firmware, cleaning the cache and implementing new rules, but the problem persists.
I would appreciate any insights or experiences that you may have regarding this matter. Thank you.

Hello

Does it happen in flow mode as well?

What do you see when you test rating lookup?

It should match when you do it from your FG and from FortiGuard. Does it match?
