AWS S3 ListObjects Access Denied Troubleshooting Tips

It allows the IAM entity to list all of the bucket’s objects. The S3 error ” when calling the PutObject operation” occurs when we try to upload a file to an S3 bucket without having the necessary permissions. When your data is being encrypted in S3, it could be done via a KMS key which your user would need access to as well to decrypt the objects. Find out what role you are using and double check the permissions. If this is not a root account, ask your administrator.

Don’t attach this policy as a bucket policy. Rather attach it to the user that is trying to upload files to the S3 bucket or to the corresponding role (e.g. of a lambda function or EC2 instance).

Unable to grant public access to an existing S3 bucket?

If your IAM policy is configured correctly and you still can’t access your S3 bucket, there might be an issue with the Bucket Policy.

We allowed the GetObject and ListObject actions to a specific user in the account . The first statement in the JSON policy allows the GetObject action on individual objects in sub-directories of the bucket. Once the policy is attached to the IAM entity, you will be able to upload files to your S3 bucket.

Furthermore, check if there is a condition that permits only a particular IP range to access bucket objects. However, if the user or role belongs to the bucket owner’s account, we need permission only from IAM or the bucket policy.

Solution

As the key pair is created, save the new credentials to a safe place for further use. LIA InfraServices goes the extra mile, in more ways than one, to support your IT needs. Making statements based on opinion; back them up with references or personal experience. So Simply add a S3 Policy to you IAM User as in below screenshot , mention your Bucket ARN for make it safer and you don’t have to make you bucket public again. If you have an encrypted bucket, you will need kms allowed. Share a link to this question via email, Twitter, or Facebook.
