Python

When trying to connect to a database with this python code to test the connection.

import boto3
s3 = boto3.resource('s3')

for b in s3.buckets.all():
   print b.name

I am getting this error thrown at me.

Traceback (most recent call last):

botocore.exceptions.EndpointConnectionError: Could not connect to the endpoint URL: "https://s3.us-east-5.amazonaws.com/"

The strange part is that the connection was working earlier in the day and then at it stopped working the same thing happened to me yesterday at the same time so I am assuming it is a network configuration issue. This question is the only one that is similar the solution the original poster stated was to unset both HTTP_PROXY and HTTPS_PROXY which I attempted but it did not work.

Answer

You have configured AWS env incorrectly. Check your ~/.aws/config file. You must have configured it incorrectly as us-east-5 which is an invalid region. Change it to us-east-1. Or run aws configure command again and specify the correct region.

[default]
region = us-east-1

Exception in Boto3 – botocore.exceptions.EndpointConnectionError
