Audio plays in one section of apartment but not the other

I have Sonos Connect pre-installed in my apartment. There are speakers in the living room as well as the bedroom ceilings. Since the beginning both have always played together and I’ve never distinguished between the two in settings or anything. But I just noticed that the bedroom speakers are not playing any audio. I’ve also been having problems with music dropping off for several seconds and then coming back on. 
 

Can you tell me what I need to do to get the music playing again in the bedroom? Have already tried unplugging the power of the Sonos box for 10 secs and plugging back in.
