Signed out of Apple ID, signed back in and don’t have my playlist or any of my songs in my library anymore?

so I had to sign out and then I signed back in like I’ve done a hundred times before and it always loaded my library and my playlists again but not this time? Tried closing the app and opening it again and restarting my phone but it just won’t work. And then when I click on a song and want to add it it just says cannot connect? I have an Apple Music subscription and I don’t get any ads for it so that’s still in the system but nothing is working?

please help!
