How can a site with ssl access the backend without ssl?

Answer 1

You can implement proxying on the side of your backend/server. Easiest way with nginx:

location /proxy {
    proxy_pass http://domain.com;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Real-IP $remote_addr;
}

Answer 2

If you can access the backend from the site (in the browser), then this is in fact not a backend. And, accordingly, you need to configure HTTPS for it, then the problem will be solved.
