Hi,
Thank you for your interest in BubbleUPnP.
The log shows that the failure is caused by TIDAL returning http
error 401 ("Unauthorized") when BubbleUPnP
is requesting the playback stream URL.
This is unusual, but could be caused if some tracks are not
available for streaming in your country.
When this problem happens again, can you check if these tracks are
playable in the TIDAL app
or the TIDAL web player ?
This error can also happen if you are at the same time you are
playing a TIDAL track elsewhere (for example in the TIDAL app or
web player).
Best regards,
Bubblesoft
