I keep getting that error: failed to play the requested content is not loading" after a song finishes. Its really annoying especially working out. Im considering switching to Spotify but ive had this account for about 7 years on a family plan.

Hey there, 

Have you tried all the steps indicated here? 

It’s the Data and Storage Smart Cache, thanks to Dixon, it was an easy fix!  :) 
I set mine to 100GB, but I have a lot of mem!

Same issue here - tried to clear cache in the settings but didn’t work! 

So in the Deezer APP try this….

clear all downloads, close app, try and force close all the way if you know how. Reopen, and find your settings in the Deezer app for audio quality, set to what you want, then find the data storage settings and set the amount of buffer, it’s called smart buffer and crank it up, say add 50    Then close out again,.  Open and start picking songs to download.   that should do it. 
 

I had the same issue today in the Windows app and the web app on my desktop. The following fixed it for me:

start > run > cmd

type in the following

ipconfig /flushdns

and press enter

After that i restarted the app and music worked again.

edit: nevermind, it's broken again.
