Root Cause

S3 bucket/object permissions deny access. Involves IAM + bucket policy + ACL + block public access.

Workarounds

  1. 92% success Check IAM policy allows s3:GetObject on the specific bucket/key ARN
    arn:aws:s3:::bucket-name/*

    Sources: https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-with-s3-policy-actions.html

  2. 88% success Check bucket policy isn't explicitly denying access
    aws s3api get-bucket-policy --bucket <name>

    Sources: https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucket-policies.html

  3. 85% success Check S3 Block Public Access settings if accessing from external

Dead Ends

Common approaches that don't work:

  1. Make the bucket public 90% fail

    Security risk — opens all objects to the internet

  2. Use root account credentials 85% fail

    Root account should never be used for programmatic access
