First of all thanks for reading my post en maybe helping me.
I have a Synology DS411+II which should be powerfull enough to stream SD. I just want to try if this is something I can use.
I’ve downloaded PlexMediaServer-0.9.16.3.1840-cece46d-x86.SPK and installed it manually on my Synology. This was going fine. Now I’ve opened the url (the_ipaddress:32400/web) and it keeps hanging on the left site with the following message:
Looking for servers
A server could not be found.
Download and install Plex Media Server,
and it will appear here.
I have no idea what I’m doing wrong.
Can somebody help me please?
OMG finally, Thanks trumpy81 !. It’s been a whole day I have been searching for an answer on why the damn server couldn’t been found. I upgraded DSM, upgraded Plex, to no avail. But this - deleting that Preferences.xml file worked.
Sorry for my late respone. But I deleted those two files and after that Plex woun’t start anymore.
He made a new preferenses.xml but not the other file.
It failes to start now.
I also don’t think this is the answer for me because I also tried reinstalling plex multiple times and deteled the whole plex folder.
If I remember correctly I should get some questions during the installation wizard about the account.
I dont get anything. So how is my server added to my account. I can’t see my synology in devices.
@trumpy81 - I’m also running into this problem with my DS416play. Not sure exactly what happened by now i’m in the State where plex is just “looking for server” forever. I’ve tried deleting the aforementioned files as well as doing a full re-install per your Q7 steps and that didn’t work.
Now, go back and restart Plex on your NAS and open it in your browser… I tried this one also, no success. it seemed to have no effect. also I should note that i didn’t find any “other” place to log in besides the initial log in screen. I tried settings → general but there was nothing there to log into
Make sure you turn off Jumbo Frames, see Q4 on the Synology FAQ’s page, link in my signature. DSM 6.1 doesn’t even have a jumbo frames option in the Network config - no action there. Or did they move it?
if you have any port forward rules for Plex configured in your router, remove them temporarily done. still no results
If you have used the DSM EZ-Internet wizard at all I’ve never used it however I did use upnp at some point. Should I still reset it?
Lastly, to ensure clean state, i’ve put my Synology in DMZ turned off the DSM firewall and still nothing
Is the port being used port 8200? that wasn’t in the Plex listed ports from your Q4
Thanks @trumpy81 so much for the help! I really do appreciate your time here
See the image below and note the default value for MTU is 1500 I’m able to check the box to set it manually, however, It will only let me set it to 2000. When i choose 1500, it seems to reset back to unchecked box and 2000 grayed out
and make sure the MTU is set to the default 1500 there also Done
You should turn on uPnP in the router. Done
If your DSM Firewall is enabled (recommended) then do open the ports used by Plex. I open all ports to the NAS, as shown in the second image below, but that is up to you. Done. I opened up everything like in your image
Is the NAS local to you (IE: in the same house) or is it located at a remote location? The NAS is at my house but accessing it outside doesn’t seem to change anything. I’m accessing it by using OpenVPN
After doing all the above AND using your steps to re-install, still “looking for severs”
looking at the logs, i’m not convinced there i a communication issue. I believe the error you found earlier is just something related to a general scan on the network.
Since I’ve assigned a local hostname to my Synology, it was also being used for the Plex server. But Plex seemed to not be able to understand my hostname… when i popped in the actual IP of the Synology it worked…
I feel like such an Idiot
Thanks again @trumpy81 for your help here. Much appreciate it!
I would just say make sure to note that fact to “always access Plex with the actual IP and not a hostname” in addition to the updated MTU size setting on DSM 6.1
Hello, I’m almost having the exact same problem. Except I never use the hostname. always use IP. My plex has been working fine for the past couple years and now suddenly just keeps saying “looking for servers”. This is while I’m logged in directly to the IP address of the server and signed in! I’m currently running the latest plex and rebuilt the database to no avail.
Yes, did all the Steps. I decided to reboot every piece of equipment in my house. which is significant. Synology DS3612XS, 10GBE switch, 8 port gigiabit switch, Router, DNS server then finally the Synology. (Which i feel like I’ve rebooted everything already individually already). Surprisingly it did the trick. So apparently it was a network issue. Thanks for you help!
I might add that it is indeed ddd with the latest version of plex it requires a connection to login into the local server console. On the old version you could get right in. Even if your connectivity was completely botched.
