AWS S3 Bucket Policy Not Allowing Access from CloudFront Origin despite Correct Configurations
I'm getting frustrated with I tried several approaches but none seem to work. After trying multiple solutions online, I still can't figure this out... I'm currently working with an scenario where my AWS S3 bucket policy isn't allowing access to my content from a CloudFront distribution. I've configured the S3 bucket with the following policy: ```json { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::cloudfront:user/CloudFront Origin Access Identity E2EXAMPLE" }, "Action": "s3:GetObject", "Resource": "arn:aws:s3:::my-bucket-name/*" } ] } ``` Despite this, when I try to access the objects via CloudFront, I receive a `403 Forbidden` behavior. I have also made sure that the origin settings in the CloudFront distribution are correctly pointing to the S3 bucket. The distribution status is ‘Deployed’, and the cache behavior is configured to forward headers, cookies, and query strings, so everything seems aligned. To troubleshoot, I also checked the CloudFront logs, and I noticed entries like: `[behavior] 403 Forbidden - Could not access the S3 bucket. Check your permissions.` This leads me to believe that the IAM role for the CloudFront origin access identity might be misconfigured, yet I’ve validated that it should have appropriate access. I’m using the AWS SDK for Java (version 2.x) to interact with the resources. I have double-checked that the bucket name is correct and there's no typo. As a last resort, I also tried granting public read access to the bucket just to see if that resolves the scenario, and it does, which is puzzling since I want to use the origin access identity. Does anyone have any insights on what might be wrong or steps to further diagnose this scenario? Any ideas what could be causing this? This is part of a larger service I'm building. What am I doing wrong? Any examples would be super helpful. This is for a microservice running on Ubuntu 20.04. Has anyone dealt with something similar?
