Environment
Running Confluence or Synchrony in AWS
Using AWS for node discovery
Cause
There is an issue with the IAM role configuration in AWS. In this example, there was no profile assigned to that role or the role name is incorrect.
Solution
Resolution
Ensure the IAM role is created properly and that a profile is associated with that role: Using an IAM Role to Grant Permissions to Applications Running on Amazon EC2 Instances.
