What about deactivating all extensions except the stock ones and then reenabling them one by one while testing the mobile performance after each step?

i will make a try for sure, not sure if i want to disable extension on a site in production XD

Justoverclock not sure if i want to disable extension on a site in production XD

How many people visit your website in the middle of the night? The whole thing wouldn't take longer than half an hour.

Or you could try to pin down the problematic extension(s) locally.

I will do that tonight. But why is good for desktop and not for mobile ? An extension could affect only the mobile side?

I tried a test from my end on your Flarum. It says

and for Flarum.org

You have different results for mobile compared to desktop because pagespeed uses different metrics for them, on mobile it simulates (more or less) a 3G connection on a low end smartphone (the target years ago was a Motorola Moto G4, I don't remember if they changed it in the last update), desktop instead has better specs so things that slow down the smartphone aren't as significant there.
From a quick look of your results it seems that the biggest culprits of the slowdowns are font-awesome and google tag manager, the server response too isn't really the best one, what are you using to host your forum?

wonderbeel i'm currently on siteground. and i've put some css to hide header (and font request) on mobile....but nothing changed, even without header i get a bad score.

but i think (on my phone for example) that the forum is really fast.
