GTmetrix tells compression is not active !

Hi
with the latest WP and W3TC installed on a php 7.x Plesk server where I’m 100% sure mode_deflate is installed GTmetrix still says the compression is not active !

moreover the W3TC compatibility check tells

mod_deflate: not detected
mod_env: not detected
mod_expires: not detected
mod_filter: not detected
mod_ext_filter: not detected
mod_headers: not detected
mod_mime: not detected
mod_rewrite: not detected
mod_setenvif: not detected

and each of these assessment is wrong

Where should I look at please?

thanks

Cyril
