The "Bucket Access Must Be Addressed Using Specified Endpoint" error occurs when trying to access a bucket on a cloud storage platform (e.g., Amazon S3, Google Cloud Storage) using an incorrect endpoint. An endpoint is a URL that represents the entry point for a cloud storage service.

This error is often encountered when the bucket is in a different region than the default endpoint in the client configuration. To fix the issue, you need to update the client configuration with the correct endpoint.

Let's dive into the causes of this error and how to fix it.

Causes of the Error

The primary cause of the "Bucket Access Must Be Addressed Using Specified Endpoint" error is an incorrect endpoint configuration in your client. This can happen due to the following reasons:

  1. The bucket is in a different region than the default endpoint specified in the client configuration.
  2. The client is configured with a custom endpoint that does not match the actual endpoint of the bucket.
  3. The client is configured with an incorrect endpoint URL format.

Step-by-Step Solution

To fix the "Bucket Access Must Be Addressed Using Specified Endpoint" error, follow these steps:

Step 1: Identify the Correct Endpoint

First, you need to identify the correct endpoint for the bucket. You can find the correct endpoint in the cloud storage service documentation, such as the Amazon S3 documentation or the Google Cloud Storage documentation.

Make sure to choose the endpoint that corresponds to the region where your bucket is located.

Step 2: Update Your Configuration

Once you have identified the correct endpoint, update your client configuration with the new endpoint. Depending on the SDK or tool you are using, this process may vary. Here are some examples for popular SDKs and tools:

AWS SDK for Python (Boto3):

import boto3

s3_client = boto3.client(


Update your ~/.aws/config file with the following content:

region = your-bucket-region
s3 =
  endpoint_url =

Step 3: Test the Connection

After updating the configuration with the correct endpoint, test the connection to ensure the issue is resolved. You can do this by performing a simple operation, such as listing the contents of the bucket or downloading a file from the bucket.

If the operation is successful, the error should be resolved. If not, double-check your configuration and ensure you are using the correct endpoint.
