The problem is it’s not a network problem, not a CPU problem, and not a server problem. It’s just an Android client player bug that has nothing to do with you or your hardware.
Don’t worry though, it’s only been 18 months, I’m sure it’ll fixed any day now 
I had this happen to me yesterday with a new Android box for TV , “Your connection to the server is not fast enough to stream this video.”, first time I saw that, and it surprised me. But then I got to thinking, my server is on my 5Ghz, my new box was on my 5Ghz and my roommate’s Roku was on the 5Ghz, So I switched my new box down to 2.5Ghz, the message has not returned today so hopefully that was it.
18 months? Sorry, no. I just switched to emby. Works flawlessly.
This isn’t true at all, we are constantly making improvements to the players performance which fixes similar issues for different users. In other cases they have been Android OS issues (fixed by updates to the firmware on devices), server issues fixed by PMS updates and many client improvements.
It’s taking a while to fix all the problems and understand what is going on, as the hardware being used, network and server setup seem to impact the issues. The evidence in this thread seems to point to a server issue.
I’m submitting reproducible examples of the “Your connection to the server is not fast enough…” in response to @MwC_Trexx’s 02/17/2019 post.
In all 3 examples, the videos play for about a minute then freeze with the “Your connection…” dialog.
All examples were run with the same result. Sample #1 .mkv, Sample #2 .mkv, and a Sample #2 .mp4 created by Optimizing. All were then immediately opened and played in Android VNC without problems from their plextvshows directory on the server over the same network.
Server logs were captured and are included as an archive. I don’t know how to get Android Client logs. No networking logs (they seem to be only setup for wifi). Nothing shows at the Plex address port 32500.
120 second sample files were created from Sample #1 and Sample #2. It was too difficult to generate a sample of the optimized .mp4 Sample #2 using the command line.
Plex Server 1.16.3.1402 is on Ubuntu Linux Ubuntu 18.04.2 LTS (GNU/Linux 4.15.0-54-generic x86_64)
Android Plex Client 7.17.4.11141 (37f5ea35) is on Android 6.0.1
Wired Ethernet connection. No WiFi.
Could not upload the archive of samples files here, so instead from Google Drive Sample Files.zip

Are you not able to reproduce this issue? After 18 months of this being unresolved, why not just catch a flight for a day to someone’s house in this thread and research it first hand?
So do you think that if the people in this thread who are having problems roll their servers back to 1.14.x or 1.13.x that their problems will go away? Because I think a lot of people would do that in a heartbeat if it meant they could avoid this entire class of bugs.
Thanks for the samples! Information on grabbing the Plex for Android TV logs is available here: https://support.plex.tv/articles/201573117-android-android-tv-fire-tv-logs/
If the server is indeed the problem then that could help, however depending on your setup / situation that might not be the problem.
The issues with this that we can replicate, we have been able to fix. The ones we can’t replicate is what is proving to be difficult. Sadly their is thousands, maybe millions of hardware combinations with Android and it’s taking us a while to figure out the issues.
I tend to agree here and have thought this for a while.
Recently it also happens on the ATV 4K. Far less frequently it has to be said.
I can binge watch my 4K HDR Remuxes all day (from either local or remote storage) without issue. (Circa 50-90Mbps)
I can then play a local stored 1970’s SD TV episode at around 1Mbps and get the message two or three times in a 25 minute episode.
Sadly I have never bothered rolling back the server. The ATV 4K is my go to device nowadays and I may see the message once every few days at worst. With the Shield it could be 5 or 6 times every day, or indeed 5 or 6 times in a 2 hour movie, or not at all for a few days.
It certainly didn’t discriminate by bitrate.
You guys have my sympathies. 
Don’t suppose you could share a sample that replicates the issue as well or the episode in question? Feel free to DM it into me.
Would be curious to know if you have refresh rate switching enabled, or if you have automatic quality adjustment enabled? Both are in the settings for the Plex for Android app.
Are you on a Linux server as well?
Server wise both. My local server is Windows.
Remote is Linux. Though I personally only use the local Windows one.
Refresh rate switching is on with both the Shield and ATV 4K.
Automatic quality adjustment is off on both servers.
Would love to offer a sample but it’s just not that easy. That’s exactly how intermittent it is.
I actually tested this out a while back. A particular episode may be an issue one day with constant “connection not…”messages and the next day it will be fine.
Play a few episodes without issue. Repeat one of those episodes and “connection not…” all over again.
Interesting, will give this a try and see if I can replicate. Think your the first to mention running a server on Windows, but that’s useful to know it’s not just a Linux server problem, thanks!
Well I will add that, although my setup has now changed since UNO, most of the HDR remuxes were on the remote Linux server.
I seldom saw the issue and purely put it down to streaming such high bit rate files when it did happen.
Everything else was played back on the local Windows server and that’s where the issue arose mostly.
I will also say for the first 6-12 months of the issue being reported I never saw it happen once.
Then suddenly it struck.
I’m off work tomorrow so am more than happy to switch out the ATV for the Shield and see if I get any occurrences if it would help?
Sorry plex, but I have had enough now. Been a plex user and promoter for years, one of the first plex pass members, but I woudl like to watch my shows without constant stuttering, freezing and issues.
I have loaded emby, since other report it seems to be working, and come back to plex maybe some day in future.
Whatever you guys did in last 6-12 months, broke plex.
For those of you that want to know what is really going on visit the nivida forums. The link has been posted multiple times by different people above. Nivida has no issues advising people what is going on and where things are in the process. They also do not let their users hang out to dry for months on end without responding or updating. They are open and responseive. Unlike Plex Support.
I’m running on Windows 10, I had this issue start 2-3 days ago. It happens on both my Vizio TV(Hardwired) and my Fire Stick(5G WiFi, 4ft from the dongle), so it’s most likely the server for me. It only happens when I stream 4K.
I did upgrade my internet last week, but I doubt that’s the cause as I’ve doubled my speeds, and it’s happening to a large group of people.
On my Fire Stick the playback will lock up completely for 15-20 seconds.
On my TV the audio drops out and the video chunks along at about 1fps. Rewinding the video doesn’t add the audio in right away ether, I have to rewind it 4-5 times to have the audio…audible…
I don’t know how I’d go about generating a log with all the info you need, but I can 100% replicate the issue on demand by literally playing ANY 4K file.
I’m getting this issue now! Out of nowhere 2 days ago on my Shield and Apple TV 4K when playing high bit 4K REMUX’s. For nearly 2 years I have had zero issues now this msg comes up every few seconds or minutes depending on how big the 4K REMUX is.
Server Windows 10 Pro
Everything direct Ethernet Gigabit connection
On Latest beta Plex server.
Everything Direct plays locally on my setup, no transcoding.
Shield latest public Plex app (hdmi pass through on, refresh rate On)
TVOS latest Plex app beta
I’ve tried everything! 5ghz Wi-Fi, rolled back different server versions, changed cables. Uninstalled Plex client updates. Installed the Shield 7.3+ beta.
Definitely not my network because I can direct play all my high bit rate 4K REMUX’s using infuse on my Apple TV 4K! Which funnily is directly connected to my plex server!
Also just tested and I don’t get any issues playing the same 4K HDR Remux on iOS using the Plex app, and that’s on 5ghz Wi-fi!
Please Sort it out Plex! I heard about this issue for nearly a year here but luckily for all that time I never saw this msg, the fact out of nowhere this has hit both my shield and Apple TV 4K at the same time is unacceptable.
I’m the same. Never (hardly ever) had the problem but with PMS 1.16.3 on my QNAP I have constant buffering to my Apple TV which has an actual download of 70Mbps so network is not the problem.
Yea, I mean I can stream 4K UHD content over wireless to my Fire Stick, but I’m not able to stream on a local network?
Adding another “me too”. This showed up on my Shield recently, using UNO. Stuff that previously played now just freezes and says my connection isn’t fast enough (LOL).
I haven’t tested this on FireTV yet but can do so later. The Rokus are fine.
