"An error occured while attempting to play this video." Synology

hmm, yeah I’ve done that a few times, i’ve also uninstalled plex and deleted the share and started from scratch a few times, still have the same issue

all devices are on same subnet

plex works between laptop and synology but not fire tv and synology

but windows server to laptop and windows server to fire tv works fine. so not a router issue
no firewall enabled on synology

i’ve now again completely deleting plex share, reinstalled plex,re added the server to my account.
same again plex htcp works within minutes. firetv app says “an error occurred while attempting to play this video”
whereas the plex windos server has no issues and videos play.

all same subnet. plex htpc works for both servers, firetv only works for windows server
