Hello Stelix-Inc,
To confirm, is Music the only app showing this error? For example, are you able to visit websites in Safari when this message appears, load content in iTunes, the App Store, and other data enabled apps? The reason we ask is to help isolate the issue and ensure the right troubleshooting steps are performed. If the issue is only with the Music application, you'll want to complete the steps listed below as they're specific to resolving connection related issues with Apple services. You can also find these steps outlined in more detail via the following link.
- "Check the system status page"
- "Make sure that your device is connected to the internet"
- "Update your software"
- "Check the date and time"
If you can't connect to the App Store, iTunes Store, or other Apple services
Take care!
