As you don't specify the port in upstream {} block nginx uses the default 
which is 80 ( 
http://nginx.org/en/docs/http/ngx_http_upstream_module.html#server )

Also for secure backend connection you should enable proxy_ssl.

Reading https://www.nginx.com/resources/admin-guide/nginx-tcp-ssl-upstreams/ 
should probably be a good start.

It seems you have taken the default configuration example but if you use 
nginx as a balancer without serving any .php (or other) files you actually 
don't need those *.php etc locations  - a single location / {} will do the 
job (means all requests go to backends).

For example:


http {
   upstream myappliationsite.net {
       ip_hash;
       server backendappsite1.net;
       server backendappsite2.net;
       server backendappsite3.net;
   }

server {
   listen       80;
   listen       443 ssl;

  server_name myappliationsite.net;

location / {
    proxy_pass   http://myappliationsite.net;
    proxy_set_header HOST myappliationsite.net;
}
}
