I've had Sonos for over a year plus have been a Spoify premium account holder for over a year.

Spotify used to work fine on my Sonos, but has recently shown 'cannot play track', some message that the connection is  not sufficient of bandwith insufficient.

I am sure there has not been any changes on the configuration.

If I run with speedtest.net I have at least 8Mbps  (up until 20) connection.

Could anyone help me ?

1 - How can I detect and secure that the connection is sufficient for spotify?

2 - Are there any specific configuration settings on Sonos, Spotify, Network which are to be checked / set?

3 - Since I read in the other posted messages, that other users are suffering from the same, is it possible that it is releated to the growing number of users (so more on Spotify server side)?
