This error message typically indicates that you are trying to access an Amazon S3 bucket using an incorrect endpoint.

To resolve this error, you should ensure that you are using the correct endpoint URL for the region in which your S3 bucket is located. The endpoint URL should follow this format:

https://s3.Region.amazonaws.com

where "Region" is the name of the region in which your S3 bucket is located (e.g. us-east-1, us-west-2, etc.).

To find the correct endpoint, you can consult the AWS documentation or use the AWS CLI to list the available endpoints for a specific region. For example, you can use the following command to list the available endpoints for the US East (N. Virginia) region:

aws s3api get-bucket-location --bucket your-bucket-name --region us-east-1

This command will return the endpoint URL that you can use to access the S3 bucket in that region. Once you have the correct endpoint, you can update your code or configuration to use it instead of the incorrect endpoint.

If you are still having trouble accessing the S3 bucket after verifying the endpoint, you may need to check the permissions and access policies associated with the bucket and your AWS account.
