AWS Invalid Credentials Issue — Time Sync Resolution

🧩 Problem Overview

While using AWS CLI, you might sometimes face the following error even when your credentials are correct: An error occurred (AuthFailure) when calling the DescribeVolumes operation: AWS was not able to validate the provided access credentials Example: aws ec2 describe-volumes –profile mycred

This error can be deceptive — it’s not always about wrong keys or permissions. In many cases, it’s caused by a time synchronization issue between your local VM and AWS servers.
