Apple Music "The network connection was lost"

Hey,

About a month ago, I found a song I wanted to add to my library. When I tried to play it, I got an error message saying, "The network connection was lost." I can add the song to my library and download it, and only then can I play it.

I've heard of many people experiencing the same issue, and restarting their router usually fixes it. However, that doesn't work for me. It's worth noting that I can switch off my Wi-Fi and use my mobile data to listen to the song without any problems.

Music is really important to me, and I pay for a subscription.

Can anyone help me resolve this issue?

Thanks!
