How to configure backend access via SSL in nginx?

Question

Nginx

You need secure access to the backend. The solution is represented as a reverse proxy on nginx.
I have experience using nginx with http-proxy and unix sockets.
What are the possible problems with https-backend?

What to write in the nginx config besides:
proxy_pass https://my.secured.backend;

Answer 1

If the backend works on https, then nothing. Everything else is the same as for http.
