I didn’t receive payout from 1 out of 4 devices last month. I’ve complained about that a week ago and ever since I’m not getting rewards for any ads that I get as well:
Windows 10 [Browser Version 1.33.106 ]

Have you been able to successfully receive payments in the past? Yes
Are you using a VPN? No
Are you in a supported region (see here for list of supported regions)? Yes
I had the same problem. In my case it was a Joystick in one of the USB-Ports which affected the rewards system. If you have plugged devices in your USB-Ports try to disconnect them and look if you then receive ads again.
