Can't setup PMS, "Plex Media Server not found, please install"

[madballster]

Server Version#: PlexMediaServer-1.18.1.2019
NAS: synology 415+

I have tried setting up both via downloaded (latest) package from plex.tv and with the stock Synology package that is available in the DMS package manager. Both end up with plex complaining that “server is not running, please install”. I made sure it was running though:

root@DiskStation:/var/packages/Plex Media Server/scripts# ./start-stop-status status
Plex is running

1. I have rebooted the NAS multiple times as this was mentioned by some here, however, I had no success.
2. I have removed the Plex shared folder, removed the plex user before trying to reinstall multiple times. No success.
3. I have elevated the Plex user access from ‘custom’ to ‘read/write’. No change in behavior.
4. I am on the same local network as the NAS. NAS IP is 192.169.1.100, my Windows 10 PC is on the same local subnet. I have tried both Chrome and Firefox to enter the setup, but the setup wizard never appears.

Attached please find the log/setting directory zip:
Plex Media Server.zip (1.6 MB)

Thanks for any pointers.

What you are seeing in the browser isn’t directly related to the server (unfortunately).

1. Sign the browser OUT of your plex.tv account (upper right).
2. If you can clear the Plex tokens in the browser, do so, else open an incognito browser window after signing out
3. In that incognito window, open http://ip.addr.of.syno:32400/web

Now talk to it.

If your LAN is RFC-1918 compliant (192.168.x.x, 10.x.x.x, 172.16.x.x-172.31,x.x) it will be fine. Anything else requires SSH tunnel due to being non RFC compliant for home Private Network (see Wikipedia)

I see you’re also using IPv6. If you don’t need that, it will help to turn it off but not required .

You’re spot on. Obviously my network 192.169.xxx.xxx is not RFC 1918 compliant, even if PC and NAS are on the same network. A simple SSH tunnel (I used secure CRT) solved the problem. Thank you so much.

Hello, I guess I have the same problem. I can’t connect to my plex server when I am outside my network. I can go the plex web page because I have redirected only 32400 port. but the web page indicate that no server is found.

whereas when I connect to my plex server in my own network then plex webpage indicate that a plex server is found.

what is the problem ? is it a problem of port redirection ? or is there a problem with the “freenom” service that I’m using to connect to my plex server instead of using my external IP ?

[iostrym]

Any idea ?

Is there another ports to redirect ?

More info : using Plex in my local network with 192.168.1.x address, it I’ll work but using toto.tk adresse from my private network it won’t work (even if my box has a loopback activated to redirect toto.tk to the local ip address)

Same error each it time. I can reach the page but I have then the server error message.

Hello guys

I found a way to fix this. I had the exact same issue. I installed the application on my Synology, I allowed access to plex username to my shared folder read and write.

Then clicked open and a page to the server was opened. http://x.x.x.x:32400/web then I saw the error message saying “Plex Media Server not found, please install”.

For a reason that I still don’t know the Plex server is expecting a connection from a client within the same network. In my scenario, the PLEX server IP is 192.168.1.2 which is an RFC1918 and my clients come from 10.0.0.0/24. Someone said that this is supposed to work but it is not.

Here is the solution. I generated a NAT rule on my firewall (it can also be a NAT rule on a router) where I translated the source IP to any IP within the 192.168.1.0/24 (192.168.1.1 - 192.168.1.254).

This allowed me to see the Server Setup page.

TCP 32400 and TCP 80 need to be allowed.
