API http protocol causes the mixed content error

[Json2020]

Hi. I'm creating a web application showing stats from a farming simulator server for myself and friends. I have access to XLM files, but when I fetch the data it works only on localhost. My hosting(netlify, but others too) uses the HTTPS protocol, but developer provides XML data using HTTP protocol and it causes the mixed content error. Is there any chance to make it works on the HTTPS? Why can't they serve the data using safer protocol? Will it be changed in the future? I'm using vanilla JavaScript with no backend.

You have to seeve the content using ssl/tls (https). You can use a reverse proxy such as nginx ir haproxy to make it support tls.
