EndpointConnectionError: Could not connect to the endpoint URL: "https://logs.us-east-1.amazonaws.com/"

```

Reproduce the failure with the reported awslogs command and configuration, then inspect awslogs/core.py around list_logs, consumer, and generator, along with awslogs/bin.py where the command is dispatched. Compare the client setup with the reported botocore EndpointConnectionError; the issue is resolved when the reported command no longer fails with this endpoint error or the failure is clearly handled.
