Plex disconnects web access randomly, affects playback on all devices

Server Version#: 1.18.5.2309
Player Version#: 4.22.1

I have been dealing with Plex stopping in the middle of shows or movies and having to wait a minute or so to start again. But now it seems to be getting worse and skipping a few second in movies and shows. I figured out its a gap in the buffering, so I have to stop it mark it watched and then fast forward back to were I left off.

I have tried manually setting the port in Plex and in my router and turning off UPnP, but randomly Plex will disconnect. On screen it says “Unreachable” or “No secure connection available” in the desktop player. Roku and Smart TV just stop or skip everynow and then I will get “No connection” error.

Anyone know how to fix this?

Does this only happen when you’re watching remotely or on your home network too? If it happens at home, does the issue go away when you’re direct playing?
Can you give a specific time when this last happened to you to pinpoint a time in the logs?

Okay, for clients you’re transcoding to, you have similar log entries that I had around bandwidth dropping to zero then never properly recovering.

Do you have automatic quality adjustment enabled? Try hard setting a quality below your known outbound bandwidth and test again. Does the issue occur for clients on your local network that you direct play to?

Yes happens on all clients. My Roku is set to Force Direct Play and it does it also. I have Verizon Gigabit service I can achieve 600mbs or higher consistently. It was already set to 400mbs and if I am the only one on PMS Locally or Remotely it does it. Should I lower this setting?

I have this happen for remote connections, only after the most recent upgrade to 2309 where the configuration is now saying my server is randomly not available outside of my network

@marc0nline not much point in dropping your outbound limit, just test using a hard set quality (sounds like you could just direct play the original) and see if you get drop outs.

@cillroy can you replicate the issue and then share your logs?
