Error accessing S3 bucket (NetworkingError: Network Failure)

[ease-jdaiii]

Hi, I’m having an issue setting up the S3 Explorer with my S3 bucket. Here’s the context:
1. Setup:
• I created a new S3 bucket named abcd.abcd.com (obfuscated for privacy).
• I uploaded the index.html file to the root of the bucket.
• Permissions are configured to allow public access using the S3 website endpoint.
2. What I Tried:
• Accessing the page via the CloudFront endpoint works fine.
• However, when entering the bucket name (abcd.abcd.com) into the S3 Explorer, I get the following error:

Error accessing S3 bucketabcd.abcd.com. Error: NetworkingError: Network Failure

I also tried entering the ARN (arn:aws:s3:::abcd.abcd.com) and got this error:

Error accessing S3 bucketarn:aws:s3:::abcd.abcd.com. Error: InvalidARN: ARN accountID does not match regex "[0-9]{12}"

I even tried using the bucket’s website endpoint (http://abcd.abcd.com.s3-website-us-west-2.amazonaws.com) and received the same NetworkingError.

3. CloudFront Logs:
   The only related error I see in the CloudFront logs is a 404 for /s3_id.txt. Here’s a snippet:

{
"cs-uri-stem": "/s3_id.txt",
"x-edge-result-type": "Error",
"x-edge-response-result-type": "Error",
"x-edge-detailed-result-type": "Error"
}

I suspect this file might be required but isn’t mentioned in the documentation.

4. Additional Notes:
   • I initially tried with a CORS configuration but later removed it since the documentation states it isn’t required for the S3 website endpoint.
   • The bucket policy appears to be correctly applied.
   • I suspect this is user error, which is why I didn’t open an issue. Let me know if more information (e.g., full log entries) is needed.

Any guidance on resolving this would be appreciated!
