Hey,
I know you tried to be thorough with those specs, but what we really need to see are some logs from when the connection stutters.
Also, I’m a bit confused. Is the issue that you can connect to the server and browse, but streaming fails entirely (as described in this thread)? Or does streaming just stutter?
Also, are you trying to stream 4K/HVEC video?
I’d check/try the following:
- disable Direct Play
- Insecure connections. Should be enabled on both server and client, try disabling as a troubleshooting step.
- IPv6. Try enabling on both your router and Plex server.
- Ensure “Enable local network discovery (GDM)” is on for the Plex server.
- h264 maximum level in Plex client settings on Fire TV could be the issue.
- try disabling the “new video player” in Plex client settings on Fire TV
- check that your router isn’t the issue. Assign static
IPsDHCP reservations and whitelist devices. - make sure your antivirus/firewall aren’t interfering with Plex; whitelist it.
