Nginx proxy while reserving path

Question

http {

    server {
        listen              4443 ssl;
        server_name         {{hostname}};
        port_in_redirect off;

        ssl_certificate     /etc/nginx/ssl/server.crt;
        ssl_certificate_key /etc/nginx/ssl/server.key;

        location / {

            resolver 127.0.0.1 valid=30s;
            proxy_pass http://app1:8080;
        }
    }

    server {
        listen              4444 ssl;
        server_name         X.{{hostname}};
        port_in_redirect off;

        ssl_certificate     /etc/nginx/ssl/server.crt;
        ssl_certificate_key /etc/nginx/ssl/server.key;

        location / {
            resolver 127.0.0.1 valid=30s;
            proxy_pass http://app1:8080/my/path/;
        }
    }

}

stream {

    upstream app1 {
        server 127.0.0.1:4443;
    }


    server {
        listen 0.0.0.0:443;
        proxy_connect_timeout 10s;
        proxy_timeout 5m;

        proxy_pass $target;
        ssl_preread on;
    }


    access_log  /var/log/nginx/access.log basic;
    error_log  /var/log/nginx/error.log error;
}

This is my nginx configuration. This is part of a docker-compose setup. I proxy requests sent to https://hostname to the app1 container successfully.

Now my goal is to send requests sent to https://X.hostname to the app1 container, however to a different path.

For example:

Client sends request to https://A.hostname Nginx forwards it to https://app1/my/path/

However the path is not being preserved, it's just forwarding it to https://app1 Tried many different solutions available online, and none worked.
