Ensure your Home Assistant device has a static IP and static external DNS servers! This is important! You WILL end up having issues if you skip this step. Also, please note, setting a fixed IP in your router is NOT static.
If your running a Home Assistant Supervised installation on Ubuntu, you should check a Ubuntu manual on how to configure your ip-address/dns. I run Home Assistent Supervised on dietpi and there it is real easy.
I think I know the problem! Router gives two DNS (Where my input is one DNS). It also gives the gateway 192.168.1.1 as DNS. So problem is in router I think…
EDIT: Gave primary and secundary DNS same IP (Hassio) and now it works…
Thx, I had the same issue and put the ip in both primary and secondary worked.
I didnt to the static IP stuff but my DHCP is giving always the same IP to hassio
I’m not sure if this will be helpful to anyone, but I spent several days trying to get this to work following the default instructions.
I realized that I needed to open port 53 over udp to my router in order for it to work.
I am not sure if that was always a requirement, or if it should be a requirement.
My setup is Raspberry Pi with HA installed and the AdGuard Home addon-on and integration installed.
