Unable to use Apple Music app on my iPhone

I’ve been having issues using the Apple Music app on my iPhone across multiple days now. Every tab that needs to connect to Apple servers to get music (e.g. Home, New, Radio, Search) display an error that simply says Cannot Connect, The page cannot be loaded. Try again.

I have WiFi and Cellular data access, so that is not the problem. I have restarted my iPhone repeatedly, reinstalled Apple Music, signed out of Media and Purchases in Settings. I have signed out of iCloud and signed back in.

I also had issues in App Store where nothing would load until it eventually made me sign in again (and is now functional again). Is there something equivalent in Apple Music where I can sign in? It doesn’t make sense to have an Apple Music subscription if I cannot access Apple Music going forward.
