Account <acc number> is denied access.

Hi abdullah,

Please go through the below steps once, I hope it will help to solve your issue.

1. Check IAM Permissions

• Ensure your user or role has the correct IAM policies attached. If you're using the AWS Management Console, navigate to IAM → Users or Roles, and verify that the necessary permissions are in place.
• Common permissions you might need include * AmazonS3FullAccess (for S3 access) * AmazonEC2FullAccess (for EC2)
  • AWSLambda_FullAccess (for Lambda)
  • AdministratorAccess (if you're testing multiple services)

If permissions are missing, attach the relevant policies or update the policy to provide the necessary access.

2. Check for Expired Temporary Credentials

If you're using temporary credentials (from an IAM role or via an SSO session), these might have expired. You can:

• Re-authenticate to refresh the credentials.
• If using a role, ensure the session duration hasn't expired.

3. Validate Resource Policies

For services like S3, Lambda, or API Gateway, check the resource policies that control access. These may restrict access to certain roles or users, even if your IAM permissions are correct.

• For S3, verify that the bucket policy allows your actions.
• For Lambda or API Gateway, ensure there are no deny rules in the resource-based policies.

4. Service Quotas

Ensure you haven't hit any service quotas. If you're working with EC2, S3, or other services, sometimes resource limits can trigger access issues. Check the AWS Service Quotas section to see if any quotas have been exceeded.

5. Contact AWS Support (If Time-Sensitive)

If you're in a time crunch (e.g., for an interview), you can contact AWS Support to expedite your issue. If you're using a personal account, ensure you're on a support plan that allows quick responses.
