Apple Music app (MacOS) "Listen Now" "Browse" and "Radio" and all network features not working

All network features are currently not working on all my Mac (New iMac, MacBook Pro 16") while it's working on Apple Music on my iPhone.

The only thing that is working actually on my Mac is listening to downloaded music.

I signed out on my new iMac and I'm not able to sign in again. Trying to listen to not downloaded music is loading forever.

Do you have any clues or any tips to fix that ?

My internet connection is working great and I'm able do to anything else usual using network connection.
