Is the Forticlient deep inspection a problem?

Hello guys,

I'm working on a Forticlient EMS system.

In the last year I noticed that some sites deny the user access.

I explain myself:

sometimes the cloudflare captcha denies (the image above is just an example from internet) the user access to the websites (ChatGpt is one of them).

Now, the same is appening with the onesignal.com site:

on the EMS I have a web filtering profile with deep inspection enabled:

now, If I am not mistaken, the deep inspection makes forticlient decrypting and re-encrypting the traffic with its own certificate. I believe that this is causing the issue, but please correct me if I'm wrong.

I also added the onesignal.com site to the exemption from the web filtering, but the issue is the same.

Is anybody of you experiencing the sam issue? Any idea to solve it?

Thank you for your support.
