Nginx TPB proxy

gistfile1.nginxconf

server {
  listen [::]:80;
  listen 80;
  server_name "~^(?<thishost>[^.]+.)?(subdomain.example.com)$";
  access_log off;

  location / {
    resolver 8.8.8.8; # or whatever your server can use
    sub_filter_once off;
    sub_filter 'thepiratebay.se' 'subdomain.example.com';
    proxy_pass https://${thishost}thepiratebay.se;
    proxy_set_header Accept-Encoding ""; # otherwise content sub fails
    gzip off; # otherwise content sub fails
  }
}

502 gateway error. Works for other hosts like eztv, however. .se is changed to .org. Changing proxy_pass to http:// instead just redirects me to thepiratebay.org
