GET SPOTIFY WORKING BEHIND A PI-HOLE

In this case, the list of domains to keep out of a Pi-Hole filter to get it working is pretty short. Just add the following domains in the Whitelist setting from the Pi-Hole (v5+) admin console:
 


mobile-ap.spotify.com
apresolve.spotify.com
upgrade.scdn.co
market.spotify.com
spclient.wg.spotify.com
audio-ake.spotify.com.edgesuite.net

 
That's all.
