A deny statement in the bucket policy or IAM policy is blocking the user's access
For a complete list of Amazon S3 resources, see Actions, Resources, and Condition Keys for Amazon S3. To find the ARN for an S3 bucket, you can look at the Amazon S3 console Bucket Policy or CORS configuration permissions pages. May 15, 2017 Thankfully, you don't have to. AWS provides a policy generator tool that you can use to create the policy for you. To get started, log in to the AWS console and go into the S3 service. Now, click on the bucket for which you want to create a policy file. When you do, you will see a pop-up appear. As you can see in Figure 1, this pop-up lists the bucket's properties, permissions and management.
AWS S3 is, at the most basic level, just a key/value store.When you upload an object (file) to S3 you specify a unique public key for the object. In S3 the keys look like file paths, which can lead to some confusion since you don't need to do things like create subdirectories, etc. That ARN will ensure the policy covers all objects in the bucket, no matter their name. Now click the Add Statement button, followed by the Generate Policy button. What you’ll end up with is a JSON based policy.
Check both the bucket policy and the user's IAM policies for any statements that explicitly deny the user's access to the bucket.
Follow these steps to check the bucket policy:
1. Open the Amazon S3 console.
2. From the list of buckets, open the bucket with the bucket policy that you want to check.

3. Choose the Permissions tab.
4. Choose Bucket policy.
5. Search for statements with 'Effect': 'Deny'.
6. Modify the bucket policy to edit or remove any 'Effect': 'Deny' statements that are denying the user's access to the bucket.
Follow these steps to check the user's IAM policies: Watch dogs 2 download key generator.
1. Open the IAM console.
2. From the console, open the IAM user or role that can't access the bucket.
3. In the Permissions tab of the IAM user or role, expand each policy to view the JSON policy documents.

4. In the JSON policy documents, search for policies related to the S3 bucket with statements that contain 'Effect': 'Deny'.

5. Modify the user's IAM permissions policies to edit or remove any 'Effect': 'Deny' statements that are incorrectly denying the user's access to the bucket.
The VPC endpoint policy is blocking access to the bucket
If users access the bucket with an Amazon Elastic Compute Cloud (Amazon EC2) instance routed through a VPC endpoint, check the VPC endpoint policy. Confirm that the VPC endpoint policy includes the correct permissions to access the S3 bucket.
For example, the following VPC endpoint policy allows access to awsexamplebucket:
