iPhone home sharing not working

iPhone 4S Version 8.1.2 (12B440) using app Remote Version 4.2.1 (849) isn't connecting to my Mac Mini's OS X 10.10.1's iTunes 12.0.1.26's Home Sharing.

I have both the iPhone Remote app Home Sharing and iTunes turned on and logged in with my Apple ID.

The iPhone Remote app says:

Turn on Home Sharing in iTunes on your computer or on Apple TV using the account myAppleIDUserName@domain.com.
