Audio Key Error:Failed retrieving aes key

[YutongGu]

Using the latest version of go-librespot, I’m running into an issue where the go-librespot instance is unable to play any tracks. Below are the logs.

This seems to be account-specific so troubleshooting may be difficult and is the same issue as reported in librespot.
librespot-org/librespot#1649

I cannot reproduce this issue, as you pointed out and in the librespot thread. I assume you have a Premium account.

Do you have the same problem running librespot? Can you confirm what exact version of go-librespot you are running?

I was afraid that might be the case. I was testing with commit 63920cf. Until they roll this change out to more accounts, it may be difficult to make much progress on a fix. It seems related to them forcing certain users to using their PlayPlay DRM.
