I used to be able to use my Plex server on my Synology when the Synology had an active NordVPN connection running. Ass long as I was within my LAN, this wasn’t a problem, however, since last week, I can now only use Plex within LAN when the VPN on the Synology Plex Server is inactive.
I might have happened when they rolled out the DSM 7.1.42661 update 4 patch, yes.
Are you talking about re configuring the VPN setup? Edit: Just did, no difference.
I can access Plex just fine through DSM itrself with the VPN active. But I cannot cennect to Plex through my other devices (smartphone, Nvidia Shield and Sony Smart TV) if the VPN is active.
