Problem CSS with LiteSpeed QUIC.cloud CDN

Hello, since I have set the website with LiteSpeed CDN (QUIC.cloud), the speed is indeed fast, but some css isn’t properly downloading.

Here is what the user sees at first (screenshot from Page Speed Insights) : https://www.screencast.com/t/D0itl5L4A.

I guess there should be some exception rules to add in LiteSpeed, as anyone experimented this before ?

Thanks in advanced.
