NGINX Set allow_url_fopen=on

Hello community
Been a long time user of Nethserver and now trying to migrate to version 8. I know it’s beta, this is a home none production install. I am installing OpenGamePanel as a virtual host.

I have setup a new virtual host and installed the required web server files from a zip. I have started the install process but have hit a problem with one of the requirements.
Please see attached screen shot. Any help would be appreciated.

NethServer Version: Nethserver 8
Module: NGINX
