Hi, I'm getting the same error probably from Yesterday, too . Have you found the reason for the error?

I was having the same issue and found the solution, its looks like in your code to make request to AWS and to provide current dateTime , you may be using YYYY instead of yyyy.   
  
Since its last week of calendar and if you using YYYY it will return year as 2021 , so use yyyy it will return actual year 2020.  
  
Update date on both header :  
X-Amz-Credential and X-Amz-Date.
