Today, I noticed that most of my pocket casts won't play strangely Sirius, soundcloud, mixcloud and library all work with no issues. I have about 12 podcasts, several sources and half of them throw the error 701.
I did, today, get my outside DSL line replaced, but again it works fine for all my other services. Pocket Casts works fine from the app also. I also reinstalled the sonos app and deleted and re-added the service no change
