Personal Hotspot issue

My iPhone runs iOS 11.2.1 When I try to share the cellular data connection, the device that needs to connect to Personal Hotspot can not establish connection. The device can not get IP address. "Problem with authorization" error message appears.

iPhone 6 Plus, iOS 10

Dear all,


Thank you for your support. The personal hotspot issue is already solved. I do not know how, but it works now in a proper way. How it was before. I did not do anything.
