I do not have problems listening to tunein radio or tracks from my NAS, it seems to only be Amazon. It would suggest that the problem is not local to my network but I am happy for someone to provide a better insight.
I raised this in https://en.community.sonos.com/music-services-and-sources-228994/unable-to-play-music-6818176 but was unanswered.
I have since submitted another diagnostics 111914164 as was wondering if someone could help?

Hi there, Hoagieben. If the problem is only when you use Amazon Music, I'd recommend removing the music service credentials from Sonos and re-add it to Sonos. This will force the two to re-authorize and should get this back up and running. If you've already done this, then it might be best to reach out to our support technicians. They are able to get a closer look at your connection specifically to Amazon Music.View original
