### Error Building Component

- Error building Component Elasticsearch: Connection error caused by: ConnectionError(Connection error caused by: ProtocolError(('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))))

I found this issue happen only on specific component. I tried another component that do the same task, it work like a charm  
But, I have not been tested it for the cloud, yet
