Bamboo Elastic Agent access denied to remote objects (S3 Buckets)

When I launch my Custom Windows Server 2012 Bamboo Elastic Agent from Bamboo onDemand the instance is loaded but it can't seem to download the necessary files it needs to get the Agent working. Below is the exception from the bamboo-elastic-agent.out

I noticed this post in the answers site https://answers.atlassian.com/questions/214264/new-elastic-bamboo-agent-stuck-pending-amazons3exception-in-log
the solution seemed to be to refresh the bucket policies.
