Discovered that Plex for Mac is unable to play Videos anymore. Plex in Chrome/Safari work fine.
Plex for Mac Version 1.43.4.2971-aa2133cc
Plex Media Server 1.26.0.5715
Plex Media Server console shows an unending stream of these errors in the logs:
Failed to stream media, client probably disconnected after 16662528 bytes: 104 - Connection reset by peer
I tried Plex Media Player and saw the same behavior.
I am connecting directly over my LAN on the same subnet to the Plex server.
Are you getting any error messages?
Do you experience the same for different videos?
I just tested this on the same version (running on macOS 12.3.1) and cannot reproduce any issues (video is playing straight away without issues).
I was seeing it for all the videos I’m testing with at the moment. I just switched to a few different videos and those seem to work fine in the Plex App.
I zipped a screen recording of the spinning wheel that pops up.
Screen Recording 2022-04-26 at 7.41.25 PM.mov.zip (335.1 KB)
I tested this on macOS 12.3.1 on an M1 Max. I also tested this on an Intel Mac running macOS 11 as well.
@tom80H Any other insights? There’s nothing wrong with these videos, they play fine in browsers with Plex and on the mobile iOS app as well.
Sorry… none based on that little snippet.
Is there any further troubleshooting that you’d suggest?
The client logs might contain some helpful details.
Hi @tom80H ,
Here are the messages that pop up while playing an affected file on Plex for Mac:

@tom80H Any insight into what might be happening here?
Sorry, nothing jumping into my eye except it apparently keeps buffering
@tom80H So it looks like this is a bug? How can it be fixed?
bump
On a related note, I have noticed that this only affects the Plex App itself coming from a configured local subnet. The Plex desktop App connecting over the Internet is not affected.
Plex in the browser from the LAN or Internet are not affected so this is definitely a bug on the server/Plex App.
@tom80H How can we continue troubleshooting this?
Sorry for being of little help. As I mentioned before… based on that little snippet of a log, there’s nothing to see (except it’s buffering). The full log might show some significant detail – but I’m not really “fluent” in reading those.
@tom80H How would I get a “full log”?
server logs – probably the same location you got the snippet from 
@tom80H Yes, I know, I have been looking there and have my logging levels elevated from the last issue that I was working on with another Plex representative.
Plex Staff this bug persists in Plex 1.27.1.5916.
