The reason for this situation is that the song is not logged in to the account. It needs to be played again after logging in to the account.

QQ Music failed to obtain the playback link at 1:43, which means that when using the QQ Music API interface to obtain music, the background request was successful, but 403 prohibited access to the page occurred, resulting in the inability to play music. You need to log in to the backend to reset the login status of your account.

When QQ Music obtains the playback link, it should obtain the link from the correct URL, otherwise it will not be able to play the music normally because it cannot recognize the link code.
