Plex unusable due to buffering on Mac running Sequoia 15.0.1

Plex Media Server

Server Version#: 4.138.0
Player Version#: Plex for LG, Client Version 5.88.1 Platform Version 8.3.0
I cannot work out what is wrong with my Plex installation. The symptoms are constant buffering to the extent where it’s not possible to watch anything. However, streaming using a device such as Airflow works seamlessly. I also have a lot of problems with the drives staying connected in OSX, and have sought to get around this by using a programme called Amphetamine to keep the drives awake and I use a programme called Volume manager to map establish the drives for Plex.

I can’t see any issues with hardware running out of processing power or memory and feel like this is likely to be a configuration issue.

Server
I have a 2018 Mac mini running 3 GHz 6-Core Intel Core i5 with 8 GB 2667 MHz DDR4. It’s running Sequoia 15.0.1. The device is connected via Ethernet to a 8 port hub.
Storage
All the media is on a MyCloudEX2Ultra 12TB NAS. The device is connected via Ethernet to a 8 port hub.
8-port hub
The 8-port hub is a TP-Link TL-SG1085, 8 port gigabit device.
DHCP Server / Router
The network is supported by a Linksys 2 node mesh system (MX5500 Series), the hub is attached to the child node. I obviously have no idea whether any of the network traffic needs to hit the parent node, but I would assume that it does not.
Help please! Let me know if you need more information for troubleshooting.

I have this issue too. It was not occurring under Sonoma. I suspect it has to do with Apple’s privacy settings but I’ve changed many of them with no improvement. I’m planning to downgrade to Sonoma today to see if that resolves this issue.

I too had constant buffering making video unwatchable when I upgraded from Sonoma to Sequoia 15.0.1. It was resolved by downgrading to Sonoma. I would very much like to be able to go back to Sequoia if anyone works out the underlying issue. Does anyone know if the issue is still there with Sequoia 15.2?
