Configuration fix for Synology DSM 6 reverse proxy to handle websocket

BACKUP YOUR portal.mustache BEFORE MODIFYING IT!

You need to edit the file /usr/syno/share/nginx/Portal.mustache to add the followings in the Location section:

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 86400;

Then restart the httpd with:

sudo synoservicecfg --restart nginx

This will restart ALL http service running, not only reverse proxy, as a single instance of NGinX runs everything.

A modified Portal.mustache is provided in this repo (warning: based on DSM 6.1.6-15266).
