>             Project: Apache Airflow
>          Issue Type: Bug
>    Affects Versions: 1.10.1

> Currently SFTPOperator executes:
>  
> {code:java}
> sftp_client = ssh_client.open_sftp()
> {code}
> without handling socket errors. 
> If error occurs with the connection the operator show the following message:
> {code:java}
> Subtask: airflow.exceptions.AirflowException: Error while transferring None, error: 'NoneType' object has no attribute 'open_sftp'{code}
> This error is misleading because it suggests that there is a problem with the file transfer yet the problem in fact can be with the connection.
>  
> The issue reported by lot on Slack.
