Hopefully someone can help me out on this one because i am totally lost. A few years ago my main Plex Media Server was on my NAS. It got to the point where I needed more room and wanted transcoding capabilities so i moved everything to my computer. So i currently have my main server from my computer. The NAS got re-purposed as a VPN and routing box until i gave it as a Christmas gift to my parents. I share my media with them. Recently i have been having issues with consistent internet so i am attempting to set up Plex on the NAS again so they can watch stuff locally without having to stream it over the internet. In the past i could have more than one server so if that is not the case anymore please let me know. Here is the setup i have running for my parents:
NAS: DS411slim
DMS: DSM 5.2-5644 Update 3
Plex (on NAS): 0.9.15.2.1663-7efd046
Router: Netgear Nighthawk R7000
The problem i am receiving is when i start up Plex on the NAS, and sign in, i am presented with a message where the server would normally be that says "A server could not be found. Download and install Plex Media Server, then sign the server in.". It also says it's looking for servers above that. I have shutdown my home server to keep it out of the way while i try to set the NAS up. I know i have the ports forwarded correctly. I went through them meticulously. The cable is a cat 5 that i have tested and am getting no resistance through. Jumbo frames are not enabled. No firewall rules and all ports are open on the NAS. I have attempted to open the Preferences.xml and modify it as one post told me i should try, but the only entries i see are "MachineIdentifier", "ProcessedMachineIdentifier", "AnonymousMachineIdentifier", "agentAutoEnabled.com.plexapp.agents.lastfm.Artists.com.plexapp.agents.vevo", "GracenoteUser", and "MetricsEpoch". I have uninstalled and re-installed. I have SSHed into it and deleted all of the plex directories and reinstalled everything. I am presented with the same message when i launch from plex.tv. I have tried chrome, firefox, and IE. I've tried accessing it from different devices. I haven't been this stumped in a long time.
If anyone has any ideas i would appreciate the input.
