Browser sents request on HTTPS but Nginx server running on port 82/83 receiving x-forwarded-proto/scheme as http instead of https

Nginx Port 80 config

---

http {
    ...
    server {
        ...
        listen 80;
        location / {
           proxy_set_header   X-Forwarded-For $remote_addr;
           proxy_set_header   Host $http_host;
           proxy_pass         "http://127.0.0.1:81";
        }
        proxy_set_header HOST $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Scheme $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_redirect off;
    }
}

Nginx Port 81 config

server {
    listen       81;
    location ~ ^/v1/test {
        proxy_pass http://127.0.0.1:82;
        proxy_set_header HOST $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Scheme $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_redirect off;
        break;
    }

    location / {
        proxy_set_header HOST $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Scheme $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_redirect off;
        proxy_pass http://127.0.0.1:83;
    }
}

Nginx Port 82 Config

server {
    ...
    listen       82;
    proxy_set_header HOST $host;
    proxy_set_header X-Forwarded-Proto $http_x_forwarded_proto;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_redirect off;
}

Nginx Port 83 Config

server {
    ...
    listen       83;
    proxy_set_header HOST $host;
    proxy_set_header X-Forwarded-Proto $http_x_forwarded_proto;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_redirect off;
}

Applications running on port 82/83 are rails applications and use Passenger to serve the traffic.

Even we tried setting as below in 82/83 Nginx server configs

proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Forwarded-Scheme https;
