🐛 Describe the bug / provide steps to reproduce it

Not really a bug, but a question about configuration of a reverse-proxy, so that we can be sure that the reverse-proxy is not the cause of some strange behaviours.

In the documentation FAQ (https://dozzle.dev/guide/faq#i-installed-dozzle-but-logs-are-slow-or-they-never-load-what-do-i-do) you say to add these directives to disable proxy buffering in nginx :

        proxy_buffering             off;
        proxy_cache                 off;

But here https://dozzle.dev/guide/changing-base I see you also added the chunked_transfer_encoding off; directive :

    chunked_transfer_encoding off;
    proxy_buffering off;
    proxy_cache off;

So it is a bit confusing if chunked_transfer_encoding off; should be set or not to have Dozzle work correctly behing a reverse-proxy (as I understand chuncked transfer encoding is generally useful for SSE).

Thanks a lot ;)

Personally, I don't think you need any of them because Dozzle sends X-Accel-Buffering: no which should disable all buffering.

What are you seeing? Is it not working out of the box?

Also, should I enable discussions? Seems like a lot of people just have questions that are not issues. :)

OK thanks for the answer.
We suspect our web host to have forced buffering on its reverse-proxy (even with X-Accel-Buffering header sent) and need to provide him infos on the necessary configuration on its side specifically for dozzle endpoint. I wanted to be sure to provide him the right infos.

We will try with just proxy_buffering off; then and not add chunked_transfer_encoding off ;)

Indeed it would be great to enable Discussions :)
