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 follonwings 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 6.0-7321 Update 2).
