vRA 7.3 with Amazon Endpoint

Hello Folks,

I am trying to configure Amazon EC2 endpoint on my vRA 7.3.

I have deployed a DEM Worker VM with internet access. (no proxy)

I have already created an IAM User with Administrative Permissions and I got its Access Keys and Secret access key.

I used the Access Keys and Secret Access Key which I have created to create the Amazon EC2 Endpoint on the vRA.

When I start the data collection I got a failed state and when I checked the logs I got those errors below.

Failed to run Amazon EC2 data collection. Error: AWS was not able to validate the provided access credentials.

Workflow 'AmazonEC2EndpointDataCollection' failed with the following exception:

AWS was not able to validate the provided access credentials

Inner Exception: The remote server returned an error: (401) Unauthorized.

I really don't know whatelse I can do to fix this.

I have already changed the access and secret keys but it didn't work.

Any help?!?
