Comments
After deploy on CD in Azure MediaProvider adds extension webp as a URL param. This should trigger the webp optimizer in the MediaRequestHandler. But the MediaProvider doesn’t appear to run. On my local envirement I don`t use CDN and Dianoga works fine. And I am probably missing something?

Do you have any updates about this issue?

It sounds like an environment issue so I would recommend asking in Sitecore Slack to get help.

@NStrongin

Do you have Dianoga.WebP.CDN.config enabled locally and everything is fine?
(ignore that you are not under CDN)

Only if works locally with Dianoga.WebP.CDN.config enabled:
Can you try to clean mediaCache folder on server?
You may have cache files and keys that prevents new files to be generated.

We cleared the mediaCache folder on the server after adding Dianoga.

For Azure CDN support you'll need to upgrade to 6.1.0 and review the readme config for this.
