Whenever I try to connect my Netgear X10 to a folder on my Synology NAS I get the message "Your router can't connect to your network drive because of network errors.
Is there a way to test inside your X10 admin panel that it has access to \your_synology_server\share\path?
If it does, then you should be able to enter that in folder access in Plex.
It was the firewall on my NAS, disabled the firewall for the IP address of my router and all was fine.
I am having a similar, when I Add Network Drive Connection from my netgear x10 (R9000) to my synology NAS it never fills in it just takes me back to the “Add Network Drive Connection” again. When I go into plex I can see the name that I gave it, however it does not work. I have checked the firewall on my Synology. Any other Suggestions?
