Does boto3 support VPC endpoint connection to S3

We have a Python client that connects to the Amazon S3 via a VPC endpoint. Our code uses boto and we are able to connect and download from S3.

After migration from boto to boto3, we noticed that the VPC endpoint connection no longer works. Below is a copy snippet that can reproduce the problem.

python -c "import boto3;
s3 = boto3.resource('s3',
       aws_access_key_id='foo',
       aws_secret_access_key='bar');
s3.Bucket('some-bucket').download_file('hello-remote.txt', 
                                       'hello-local.txt')"

got the below error:

Traceback (most recent call last):

Does anyone know if boto3 support connection to S3 via VPC endpoint and/or was able to get it to work? We are using boto3-1.4.0.
