You could try installing the Speedtest app from Community apps.
When you go the installed Speetest app web portal, it will give you your latency and bandwidth between your server and whatever computer you're using to access the web page.

Well first - that ain't a 4K movie, so it should have even less reason to buffer.

But you can still try running the speetest from a PC using the same conenction as your SmarTV and Shield.

I have had the same issues but it ended up being that my processor was choking on the transcode process and had nothing to do with my internet speeds. You need to determine which it is before you can figure out a solution. As was already suggested you really should install both tautulli and speedtest. Tautulli is a great app that will give you tons of good information on how your plex server is being used. You can see in real time every stream being played and if they are being transcoded or direct played. If you are using the nvidia shield and have your settings correct the 4k movies should be on direct play. Netdata would also be useful as it will show you if system utilization in real time.

I only have remuxes and 4k remuxes. Your server is too far away or something else is going on.

The buffer size is dependent on system ram. If you increase it too much, that will cause other issues.

You can currently adjust this by by running ntdrive (blitz) or ntcrypt (blitz encrypt)

My movies play with direct play just fine with just a few seconds to start.

What I found is direct stream (which is transcoding the containers) causes constant buffering. Disable Direct Stream, but keep Direct Play on.

You are also using a VPS which brings tons of uncertainty and variables, you may not have enough CPU.

@Mysterious- Install tautulli, speedtest and netdata as suggested. These are all easily installed using plexguide. When playing the video that you have problems with, tell us what Tautulli says about the video playback.

Also, give us more information about your server setup. # CPUs, CPU model, RAM, disk config (nvme, SSD, etc.), ethernet config (10gig, 1gig, etc.).

Go to the speedtest page and run the test. Tell us what it says.

You could take a stab at introducing the Speedtest application from Community applications.

When you go the introduced Speetest application online interface, it will give you your inertness and data transmission between your server and whatever PC you're utilizing to get to the page. .

Moving your device closer to your wireless router or switching to a wired connection may help improve poor connectivity. Pause the video a few minutes to allow buffering. If you're on a laptop that's using battery power, adjust your battery settings for higher performance.
