Thanks everyone for responding. I really appreciate it. So what I understand from the responses is this:
1) The Registration renewal can have a new unique value for the nonce. It can also have an empty nonce value? 2) Since this is only registration renewal, even if it fails with 401, the call should not be dropped until the original registration expires.
