Picture method uses http instead of https in docker container worpress

[sdykae]

Using the Webp “picture”, delivered images are shown as “insecure content”. webp images are delivered using http instead of https

Site is deployed in a container instance that is default exposed as 80 http, cloudflare in the middle rewrites all http to https wp database and all urls are set to https://

I suspect the pluging retrieves the request, since the request cames from cloudflare as http, plugin delivers http urls instead https.

Is there a configuration to change the deliver behavior of webp images?

Can some developer could give hints where to change the option to submit a PR to append the option
