Just bought a brand-new starter kit, flux does not find my bridge. Was the old www.meethue.com/api/nupnp endpoint updated to https://discovery.meethue.com?

I had the same problem and it took me a while to figure out it was f.lux.

Doesn't happen immediately after powering up, but rather takes a few hours before I notice it (it's on my second monitor, so it sometimes takes a while before I notice) May have something to do with the latest Windows update and/or freesync, both changes took place in the last 2 weeks Disabling f.lux and using the built-in Windows 10 nighttime mode fixes it

@herf
Same problem here - last days Windows 10 Version 1903 came in, and since then f.lux doesn't work on this monitor.

@einst3 said in classic f.lux earliest wake time:

ignore on 2. "or i close ui and reopen". still does not show wake time.

@ViwwiV did you figure this out? I'm having the same issue
