Root Cause

S3 access denied due to IAM policy, bucket policy, or ACL misconfiguration.

generic

Workarounds

  1. 92% success Check IAM policy, bucket policy, and ACLs with aws iam simulate-principal-policy 
    Identify which policy is denying access

    Sources: https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_testing-policies.html

  2. 95% success Add the required S3 permissions to the IAM role/user policy 
    Add s3:GetObject, s3:PutObject, etc. for the specific bucket ARN

Dead Ends

Common approaches that don't work:

  1. Making the bucket public 95% fail

    Major security risk; exposes all objects to the internet

  2. Using the root account credentials 85% fail

    Against AWS security best practices; no audit trail
