Question

I have seen few posts and there has been issue with config file for Endpoint connection issue, but seems my config file is ok, still facing issue my .aws/config file

[default]
aws_access_key_id=XXX
aws_secret_access_key=XXX
region=ap-south-1
output = text


>>> import boto3
>>> translate = boto3.client(service_name='translate',region_name='ap-south-1', use_ssl=True)
>>> result = translate.translate_text(Text="Hello, World", 
            SourceLanguageCode="en", TargetLanguageCode="de")

I had created IAM user with AdministratorAccess

Answer 1

I came across same error when my connection went down - botocore.exceptions.EndpointConnectionError: Could not connect to the endpoint URL: "https://ec2.us-east-2.amazonaws.com/"

When connection is restored then it worked without any issue. Probable reason for this error could be

Connection error Region is not available to cater your request as every request hits endpoint on AWS (more detail can be found on https://docs.aws.amazon.com/general/latest/gr/rande.html#billing-pricing ) It seems like Boto3 has matured enough to throw exception for more proper reason of failure to precisely know what is going.

Also if you have any issue related to your config then most of them are encapsulated with ClientError exception.

Answer 2

Amazon Translate is not available in the ap-south-1 (Mumbai) region. This is why boto3 cannot connect to the endpoint. You will need to select a supported region.

Refer to this link for the current list of supported regions: Amazon Translate Supported Regions
