        if (options.error.code === 'ECONNREFUSED') {
            // End reconnecting on a specific error and flush all commands with a individual error
            return new Error('The server refused the connection');
        }

I am having the same problem as @elstonie. The options object doesn’t contain any error if connection to Redis was lost. That happens however only when trying to reconnect for the first time, following calls of retry_strategy provide an error.

@BridgeAR thank you, I solved the problem. What I didn’t know is that in order to make this work, I have to listen to error event, or I get unhandled exceptions all over the place
