My sonos speakers (Sonos 5, Sonos one, Sonos bar - which is hard wired) all work well and all are correctly controlled by various Sonos S2 windows controllers and Sonos S2 android apps. One of my Windows Sonos S2 controllers however stopped working 4 days ago. Despite have reset the router, unplugged and replugged the speakers, and reset and reinstalled the controller numerous times, it still only recognises only 2 of my rooms, and no longer recognises my music services at all. Does anyone know how to fix this?
Once again, the speakers all work and all other controllers work perfectly well...

Just found the cure: my Sonos S2 Windows 10 controller was blocked by my F-Secure Safe software!!! The fix is explained here:
Now don’t ask me why F-Secure Safe, which is also installed on all my other Windows PC at home, does not block the same Sonos S2 controller on any other machine (including another computer just like mine)….
