You are probably using secure connections, if s,o please set them to preferred on the server and off on the app.
With Direct streaming or Transcoding , the server handles the certificates and that works, but not all models accept the Plex certificates when in direct play.
Hi Orca,
I have a couple of Samsung tvs that were working totally fine, then out of the blue began having issues where anything attempted to play on plex gave an error of “Unable to connect to the content server” . My Plex Server Security settings is set to “preferred” as you mentioned, and Secure Settings on the Samsung Smart TV App are disabled.
The only way to get them to play anythign and not give the error is to set the Player Playback to “Transcode” instead of “Auto” but that is just so intensive on the server, and those TVs before used to Direct Play pretty much everything!
Not sure what happened from one day to another. Is there anything else I can test or shoudl try?
This is one of them (2012 E-Series with Latest Firmware 2004.0):
This is the other Samsung also with latest firmware:
The most obvious would be that the file can’t be direct played by your model, but the app should tell you if so.
I know 2012 models can’t play HEVC for instance.
Also check if the server maybe has a limit set for the download speed. (it’s under remote access)
If so the server will not allow you to use more bandwidth than given, which will result in transcoding, to reduce it.
To be really sure, enable “Send Debug to PMS” and check the Plex media server.log for [PlexForSamsung] messages
They should show exactly why it picks transcoding instead of direct play.
Thanks for the Reply Orca,
I checked and I have no speed limit under remote access, and maybe I did not explain it properly.
I do not mind when it forces transcode when it needs to, its bound to happen. But what happened from one day to another a while back is that the user was getting the “Unable to connect to the content server” and absolutely nothing was playing, not a single thing, when before it played just fine, some direct play, some transcoding if it needed to, but it decided on its own. The only way to get those 2 tvs (2012 and 2015) to play anything at all was to go into player and change it from “Auto” to “Transcode” and force transcoding on everything, having it on Auto will just simply not play any media at all.
The only way I can think of, is that transcoding is needed because of certificates being used.
I know 2012 does not support playback over https, but it will still show all movies in the app.
Are you sure that the server you connect to isn’t running https?
I know for a fact both of those users’ tvs played content perfectly before, and few months ago, it just started giving that cannot connect to content server error.
Yesterday I checked to make sure on both that in the App secure connections was indeed off.
Here is the server, that also has it set to preferred, and no certificates of any sort .
I have asked the user if whenever they are home if they can change playback back to Auto and get the error a few times on different media to try and pinpoint some logs. Any other tests I can do? Those are the only ones having issues, my samsung tv works fine but its 2016 version, as well as Roku TVs. Would any custom access server URLs affect this at all?
Something must have changed. Things do not change overnight on their own.
The trick is to find out what is different now. New router, firewall, changed configurations?
Is your server logged in to your Plex account? If not, the info in the cloud could be wrong and clients may have to connect through relay, which has a bandwidth limitation.
Check how the server is listed on the client and see if that matches with your actual IP address.
I know and I cant pinpoint the issue, and unfortunately they did not tell me the exact time, just said a few months back. The only thing I can figure is that a Plex Server update at some point caused it.
-The router for sure has been stable as I have not switchced routers.
-The server is logged in to my account (should i log out and log back in?)
Where do they have to go to view how the server is listed on the client on the samsung? So i can have them send me pictures of it.
Anything specific to log? Grab the logs of them getting the errors? Change secured from Prefered to disabled? Anything you can think to try or first get some logs?
If a user connects to your server, ask them to temporarily enable the option “Send debug to PMS” and reproduce the error.
Then grab the Plex media server.log from your server. It should have lines with [PlexForSamsung] in it.
It should show, what’s happening
Is your PMS and your device on the same subnet? For example my PMS is on 10.1.11.0/24 and my TV on 10.1.10.0/24. I also enabled “Internet upload speed 6 Mbps” and “Limit remote stream bitrate 3Mbps” under “Remote access”.
I had the same problem, i also was not able to play auto or direct play and got the error with the content server.
The solution was to put 10.1.0.0/16 in “Lan Networks” under “Network”.
The PMS knows now that all devices with 10.1.x.x are on the same LAN and 10.1.10.x is not WAN for the PMS anymore and the bandwith limitation does not take effect.
I think that bandwith limitation was the cause that i got this server content error with auto and direct play.
I just wanted to share a small tidbit I found which helped me figure out what was wrong with some of my videos.
When in Plex from the browser, I selected a movie, on the same line as the length, rating, genre was a red stamp “unavailable”. I investigated further and found it was in every new video I had just added. When I added the new videos, I cheated and pointed my library to a short cut for these videos. Once I pointed the library to the correct folders, the “unavailable” stamp went away and my movies played without any more issues. I hope this helps someone with the same issue.
Hi, I am now having the same issue as listed at the beginning of this thread. I have recently changed locations, so new router, new isp, I have tried the changes listed above with no success, looking for some assistance. Thanks
After January 1, 2020 I am unable to connect to content server on my Samsung Smart TV, I have done the latest update today January 7, 2020 and nothings changed. With these kinds of issues I usually disinstall and reinstall plex in samsung app store. This time however, it has been removed from the Samsung store so cannot reinstall. This is very annoying, why was it removed ? How can I fix this???
I too have the same issue on my Samsung Q60 TV 2019 model. (on a very quick side note, samsung have changed their app coding on their TVs… the TED app is not available on my TV & after asking, TED support came back and said its due to Samsung’s coding requirements that are too difficult and not them)
anyway I also have a apple TV 4 with the plex app. (on the same network) On the apple TV app I can access my local and a remote server’s library - however there are no settings in the app to configure secure connections.
on my Samsung TV, the plex app can connect to my library securely however it cannot connect to the remote server securely. when I configure the secure connections or prefer secure connections to never or always, I still can’t connect to the remote server.
I’d be reluctant to delete the app now if it is no longer available…
HI to confirm, I had someone else confirm the latest version of plex available on the Samsung App store (in Australia) it is version 4.19.2. I too have that version on my TV, so no need to upgrade.
