Doesn't work anymore

I am on trial, and until today it worked, both local and Qobuz. It still works form my iMac to old wired B&O speakers though Audioquest Dragonfly Cobalt. But it stopped working with no reasons through wi-fi to a Beosound Edge. I did it beatifully until today even at 24/192. Tried to download again the program, but still doesn’t work, with both 1.2 and 1.3. Any ideas?
