The Failed to load font error seems to be caused by Weasyprint not supporting Woff2 fonts, as stated in their documentation.

The same error occurs for eot fonts, which is an old format for < IE9.

I have this too, very anoying:

I am running this in mm-docs docker container and I get the following output behind the proxy if it is disabled

On build server (also behind proxy, I get this)

Passing http_proxy and friends to docker container makes it like this:
