If you are receiving a 403 Forbidden error while trying to access your AWS static website, it typically means that the request is being blocked due to permission issues. Here’s a step-by-step guide to help you resolve the issue:
1. Check the S3 Bucket Permissions
AWS S3 buckets store the files for your static website, and for it to be publicly accessible, the bucket must have the correct permissions.
-
Open your S3 console.
-
Select the bucket where your static website is hosted.
-
Go to the Permissions tab and check the Bucket Policy.
-
Ensure that the policy allows public access to all objects in the bucket. Here’s an example of a policy that permits public access:
Note: Replace
your-bucket-namewith the actual name of your S3 bucket.
2. Check Bucket’s Static Website Hosting Configuration
Ensure that the S3 bucket is correctly configured for static website hosting.
-
Go to the Properties tab of your S3 bucket.
-
Scroll down to the Static website hosting section and ensure it’s enabled.
-
Verify that you have specified the correct index and error document (typically
index.htmlanderror.html).
3. Review IAM Role Permissions
If your website uses AWS services like CloudFront or other resources with an IAM role, ensure the role has sufficient permissions to access the S3 bucket.
4. CloudFront Distribution (If Applicable)
If you’re using Amazon CloudFront for content delivery, ensure that:
-
The CloudFront distribution has the correct origin settings pointing to your S3 bucket.
-
The viewer protocol policy is set to allow both HTTP and HTTPS if needed.
-
Check if the S3 Bucket Policy allows CloudFront to access the files.
5. Block Public Access Settings in S3
Amazon S3 now has a Block Public Access setting, which can prevent public access to your files, even if your bucket policy allows it.
-
Go to the Permissions tab of your bucket.
-
Click on Block public access and make sure that the relevant settings are disabled.
-
Disable
Block all public accessif it’s enabled, but do so with caution.
6. File Permissions
Check that the files in your S3 bucket are publicly accessible. Ensure that files like index.html and error.html are not restricted by incorrect permissions.
7. Clear Cache (If Using CloudFront)
Sometimes, CloudFront caches the previous error response. If you’ve made changes and still see a 403 error, try invalidating the cache in CloudFront.
-
Go to the CloudFront console.
-
Select your distribution, and then select Invalidations.
-
Create a new invalidation to clear cached files.
8. Verify the URL
Lastly, double-check the URL you’re using to access the website. It should match the endpoint of your S3 bucket or CloudFront distribution.
By following these steps, you should be able to resolve the 403 Forbidden error on your AWS static website.
