Radioplayer service still not working?

The challenge ultimately, for Sonos at least, is all that they do is point your speakers to a location maintained by RadioPlayer, they really aren’t involved as a middleman until the point at which the RadioPlayer server provides your speakers the actual data.
 

The advantage they do have is that they can read the data in a diagnostic that you tell them about, which hopefully has more details in it about the specifics as to why the connection is failing. Unfortunately, all of us, including the individual users, don’t get access to that data (likely due to GDPR and other privacy concerns).

Have had the same issue since the original outage.

Removed service, re-added service, power cycled all Sonos components, power cycled router, reset router to default DNS, was set for google. Nothing fixed the issue, still unable to browse Radioplayer service.

Have just changed router DNS to Cloudflare 1.1.1.1 and 1.0.0.1 and restarted router, Radioplayer service now back working in Sonos. Maybe something else has just been changed elsewhere and its a coincidence on timing but worth a shot if service still not working on your systems, UK based. 

Same problem. Reset my router to factory default settings & all now working. 

Same problem for me.
