Posting again to see if there are any options to try here. This is super frustrating and I cannot believe that Plex cannot perform this task or find an answer to this.
When playing music files, whether in playlist or in directory or by artist/album etc I get "cannot connect o server errors" I start playing again and it starts with no troubles. Until it fails again... I have tried rebooting the whole system with no luck.
I have a samsung 7500 series (2015) running from a qnap Ts-451+ with 8MB of ram. The network is GB and I can play UHD TV and Movies from the Qnap through plex with no issues ever. However Plex struggles to play more then 10 songs consecutively. The samsung standard player can play MP3 all day with no issues.
I have seen multiple similar postings with no answers. Is there something here that is missing? A simple setting? I have changed swtiches/ Qnap network config etc. with no luck. Happy to check everything again.
