trouble with playing on chromecast

[gans1]

Can't play Spotify on my Chromecast 2. It worked till 2 weeks ago. I've resetted the cromecast , the router and my phone. On my phone I reinstalled Spotify.

The chromecast device is appearing in the app and after attaching it the spotifysymbol is appearing on my tv but after that no sound and no display of the album or track is displayed and after a minute or 2 the chromecast is showing it's ambient screen.
