AdGuard not working on some devices

I have the strange problem, that Adguard works perfectly fine on my Pixel 5, however on an older LG V30 and my Win11 Laptop there is no sign of blocked ads in sight. Neither blocked services are working. I don’t even have a clue why the Pixel is working and the rest is not nor what to look for to fix it. Can anyone help me out?
Thx in advance

Are all your devices using the same DNS server? Are you using DHCP or fixed ip addresses? If you filter the adguard logs. do you see the ip addresses of the devices where adguard doesn’t work?

As far as I can see, yes:


  1. I’m using the DHCP settings on my router and the local dns server is set to my raspi ip address:
    Routerconfig

If you mean in the clients tab, yes I can see every device and they supposedly all have blocked content

If you mean the add-on log files, I can’t see any other IP Addresses, but I can find the error message “buffer site too small”. Might this have anything to do with the issue?
