Seems like performing a soft reset or hard reset on your speakers does the trick. We’d recommend you follow the steps suggested by @Veemaxthere and should that not work, try a factory reset. Head here to check out how.
Hope this helps. Let us know how you get on 🙂

FINALLY FOUND THE SOLUTION! None of the recommendations worked for me, until I did this. I unplugged the router (not the modem, which are separate in my house) and unplugged the power source for each set of Bose 151 speakers in my Bose Soundtouch SA-5 system, and waited a minute or so, then plugged it all back in. VOILA! Spotify worked again.
Have the same issue as on this feed and unfortunately the issue keeps coming back. Have had the SoundTouch Stereo JC II wifi system for 5 years and up to now has worked well. Apple play, TuneIn, etc ok but Spotify through both the Spotify and Bose SoundTouch Apps keep intermittently cutting out. At a loss as have tried various router settings, both direct Ethernet and a Wifi connections but same issue. Seems to have happened after a recent upgrade 2-3 weeks ago? Any help appreciated? Thx.
