Answer 1

If nginx behind proxy with https, this snippet do correct redirect for $scheme

map $http_x_forwarded_proto $upstream_scheme {
    "https" "https";
    default "http";
}

server {
    ...
    location / {
        rewrite ^([^.\?]*[^/])$ $upstream_scheme://$http_host$1/ permanent;
    }
    ...
}

And on the upstream proxy pass the X-Forwarded-Proto header like:

location / {
    proxy_set_header X-Forwarded-Proto $scheme;
    ...
}
