Hi. I installed Discourse on a CentOS server. I also use Centos web panel.

It appears that the files aren’t compressed on Discourse though it is supposed to use brotli by default and fallback to gzip.

Example for this file which is 2.2 MB:  
`https://forum.canapin.win/assets/application-301651b1c7400a000974a9cecafd44ad3304cf647cf17bcfa7af68e9ed1ac4b7.js`

Any idea why?
