Discourse not using brotli or gzip compression?

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:

Any idea why?

Is your install a standard one following our official install guide w/docker?


I followed this :
discourse/INSTALL-cloud.md at master · discourse/discourse · GitHub
And I just changed the ports in app.yml before bootstrapping the app since the port 80 was already used.

I didnt use discourse setup, I already had docker installed.

To be very precise about how I installed Discourse, here are the steps I followed:

git clone https://github.com/discourse/discourse_docker.git /var/discourse
cd /var/discourse
cp samples/standalone.yml containers/app.yml

Changed my ports here:

## which TCP/IP ports should this container expose?
## If you want Discourse to share a port with another webserver like Apache or nginx,
## see https://meta.discourse.org/t/17247 for details
  - "8080:80" # fwd host port 80 to container port 8080 (http)
  - "4443:443" # fwd host port 443 to container port 4443 (https)
./launcher bootstrap app
./launcher start app

And redirected my port in my nginx configuration in centos web panel:

That’s all.

Well there is your problem, it is proxying stuff and not passing stuff through properly.

I would recommend just keeping to our standard install which directly connects the internet to our container and handles all this stuff for you.


Thank you. I don’t know much about servers and stuff like this and I don’t know how I can achieve that. I previously used Plesk with its default settings and it was working perfectly even with nginx proxying.

I’ll try to figure this out anayway I guess.

Thanks to @Arkshine my issue was fixed.

I had to comment theses lines in /etc/nginx/proxy.inc:

proxy_hide_header Vary;
proxy_set_header Accept-Encoding '';

The server now sends the files properly compressed by Discourse:
