I have a Yamaha RX-V675 with an internet connection and connected to my router and an iPhone and Galaxy s4 both with spotify premium connected to the same router in the same network, but the receiver didn't show up as a device when i touch the button for spotify connect.

Already installed the latest firmware 1.46

Did a factory default on my receiver

Checked the connection in my network, all devices are in the same network and IP range. Yamaha receiver app works on both devices and i can also stream music with dlna from the galaxy.

Did a reset of my router, checked if upnp was on and also tried a factory default.

Still the receiver didn't show up as a device in spotify connect.
