Block Instagram app
Is it possible to block the Instagram app without having to block the entire QUIC protocol? I also can't enable "deep-inspection" because it will cause certificate errors for users (FortiOS 7.4.8).

Blocking Instagram reliably without deep inspection is tough, because the app shifts between QUIC, HTTPS and multiple CDN endpoints. Without SSL inspection you can use the Social Media category, but it won’t give you a 100% block rate.

Apparently, blocking port 443 over UDP solved the problem.
