AWS authentication requires a valid Date or x-amz-date header

Version 2.3.0 of the plugin.
I can create a repo successfully but when I try to create a snapshot, I get the stack trace below. I believe bucket and IAM roles/policies are correct. I've enabled bucket logging but haven't seen anything yet. Any thoughts?
