Having exact the same problem. Two different locations with different Yamaha devices. Tried everything but no solution so far. Have had some communication with Deezer support but now they have stopped answer. No problem for the approximatly 2 years with MusicCast and Deezer until a couple of days ago.

Hi @jedi_knight @jedi_knight, sorry to hear about the issue you're facing.

Thank you for sharing this information with us. I've already passed it on to our development team, and I'm awaiting their response.

Rest assured, I'll keep you in the loop as soon as I receive an update from them.

Your patience and cooperation are greatly appreciated.

I am having same issue. When using deezer i get one maybe two songs then drop. When i try to hit play button i feel it click but nothing happens. Have to reboot each time. 
After frustration, i play music through my serius/xm app and flow without issue for ever. Clearly not an internet issue (also my musicast is hard wired not wifi).  
my musicast and deezer are up to date for firmware

Currently, things works just fine. Playback continues, song after song.

Hope it stays that way.

I can confirm, it has been working OK since yesterday evening.

Back to listening to music and 6 songs in it is not kicking out. Hopefully a fix was done.  If so thanks deezer

I’m glad for everyone that this issue was just temporarily and that it has been fixed. Enjoy the music again 

I had a short hickup late night yesterday, but since then it has worked without any issues at all. We are all waiting for Deezer to confirm that they have fixed it.

Bye the way, they ”Deezer” acknowledged that they had problem and worked to solve the problem with MusicCast in my private conversarion I’m having with the support team.

It’s working like it should again

Hi @Sensei1, thanks for your message.

Indeed, some users have already confirmed that the issue was resolved according to information reported in a different channel:
