Nextcloud Ignoring Brotli Apache2 Module

ℹ️ Support
1

I am on Ubuntu 20.04 server, running NC24.04, with Apache2 with a Virtulamin Pro 7.1

I enabled the brotli compression module for apache2 and it appears to be functioning correctly for all websites on my server, except for nextcloud.

When I run curl -I -H 'Accept-Encoding: br' https://example.test I correctly get the following results that verify brotli compression is being used.

There is no confirmation of brotli compression usage…

Question:
How can I confirm whether Nextcloud is or isn’t using the properly configured brotli compression module for apache2?

thanks

Hello,

try Brotli Test - Verify Brotli Compression Support | KeyCDN Tools and you would have a real test

@stratege1401 Thanks for that… but it seems that the mystery deepens…

That test says that my nextcloud.com is NOT sending brotli… However, it also says none of my other websites are sending brotli, whereas url -I -H 'Accept-Encoding: br' https://example.com confirms that brotli IS being used… outputting `content-encoding: br

So now the question is who do I believe? But both test consistently say nextcloud.com isn’t running brotli

:weary::weary::weary::weary:

@stratege1401 you may want to re-think using that tool…

I just did a header check on example.com and it returned content-encoding: br, confirming brotli is running… whereas the actual brotlie test failed…

yes, i tested it too, same as you… inconsistency for CDNtools
