Spotify stopped playing on AV Reveiver Marantz SR 7009

[Sylvain_]

I had this problem 1 or 2 weeks ago and today again: Spotify suddenly stops playing music via the AV receiver and don't let me reconnect to it,

the mobile device tries to connect for est. 10 seconds, but nothing happens.

I tried:

1.) Switch the receiver off, pull the power supply

2.) Connect a LAN cable (instead of using wlan) and configured it successully in the setup

3.) Reboot of the DSL router

4.) Rebooted the mobile devices

5.) Choosen another name for the Marantz ("Living room" instead of "Home Theater", the change is shown on the mobile devices, so the spotify app finds the receiver)

Last time, suddenly, after hours, it worked again.

I lost hours of lifetime to find an error, *** is wrong there?
