Nextdns stopped working

I have set up nextdns with tailscale on my laptop and smartphone. I have set some parental control options like porn and gambling. In my nextdns console, i get a green dot “your device is ok”. So i guess my configuration in tailscale is correct (i checked the id in tailscale in nextdns, its the same).

a few days ago, i started to see that ads were coming back in games I play on my smartphone. And i can visit websites which normally should be blocked by parental control. My smartphone is connected with my tailnet (vpn connected).

is there an outage or something?
