My Plex server will not fully sync music to my iPhone



It stops at 50% saying waiting for server and when I look at the sync status on my pc it says waiting to download
It’s not a WiFi issue as I have a good constant stream usually around 50mbps

I’ve tried logging out and back in, Updating server, deleting Plex off my pc and my phone I’m now stuck ?!

Is there anything I can do to resolve this
