Hi, could you enable the logs (DEBUG=ioredis:* node yourapp.js) and post the logs here?

This is due

function isIIpcConnectionOptions(value) {
    return value.hasOwnProperty('path');
}

because I supply property path with null value

Fixed with remove null|undefined options before connect.
So it may be closed
But manual look like

Local domain socket path. If set the port, host and family will be ignored.

Fixed. Will be releaseed in the next version. Thanks for pointing this out!
