I have consistent problems with Tidal content not playing through Roon. Error message is “Networking or connectivity problem is interfering with playback” and “Transport stopping too many failures”. I have no problem streaming video content or Spotify through the system. I am running Roon via Sonic Orbiter Transporter & Orbiter and have rebooted both and have latest software.
What locality are you?
Have you tried streaming Tidal directly from the app? What was the outcome?
Have you tried unlinking and Re-linking your Tidal account to Roon? What was the result?
Thanks for suggestions. I am in CA. The issue is intermittent so unlikely to be connected to the Roon/Tidal account interface. Have not tried to play direct from Tidal.
