Port Forwarding HTTP 8080 to HTTPS 443 Domain

[user17185]

Hi
For instance I use my main apache server on my linux server on port 80 without any problems.

A Spring-Boot is running on port 8080 which is also available via HTTP not HTTPS. I need it running on https://s.example.com/

On my projects, where I don’t use Cloudflare, I add a .conf file to my Liunx’ apache server, which can for example forward https://s.example.com/ to localhost:8080, without any problems. This same config is not working for Cloudflare, and I think this is because Cloudflare doesn’t let the server know, that the request is coming from https://s.example.com/ and therefore the server is showing the default site.

The goal is just to let https://s.example.com/ to show data, which spring-boot delivers.

This is the .conf file from apache2, which has worked fine on non-cloudflare domains.
