  #  resolver 127.0.0.11 valid=1s;
  #  set $session_check_ssi off;

  expires           0;
  add_header        Cache-Control private;

  location /potree {
    rewrite ^/potree(.*) /$1 break;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_pass http://potree:1234;

    
  }


  error_page 404 /404.html;
      location = /40x.html {
  }
  # redirect server error pages to the static page /50x.html
  error_page 500 502 503 504 /50x.html;
      location = /50x.html {
