I can’t tell you the right quick fix, but there have been a couple of topics regarding the API.

Read them here:

https://en.deezercommunity.com/search?q=require%20API%20

I am very disappointed with the poor service. I want a solution for the API Auth issue. Do not oblige me to read the stuff on the community and never get a valuable answer. I am fed up with receiving answers AI. If by the end of the week I do not get an advice from a living person of flesh and blood I definitely quit and go to the competition. It is the problem of Deezer, not mine. So fix it!

Greetings.

Same here, also won't connect - Require API auth ??? 

Hi @Robert.Nađ, sorry that you are having that issue. Can you please try uninstall and install the Deezer app. It should solve the issue.

It is already solved. Many thanks.
