How to change DNS setting in Hassio

[Borto (Anthony)]

Hi,

When I installed my Home Assistant (Hassio on RPi 3+), I configured a static IP address and DNS server.

I need to change the DNS setting now and I’ve hunted around and not found out how this can be done.

Can anyone point me into the right direction?

Thanks
Anthony

Although not sure, but did you read this guide?

Guide: Connecting Pi with Home Assistant OS to wifi (or other networking changes)

Easiest method for Wifi (or setting Static IP) on HassOS If you are having problems creating a working network keyfile or importing the keyfile, this alternate method might work for you. It could also be that you have some other problem so this is not a “cure-all” for your wifi/network issues. NOTE: This method assumes you already have a working ethernet connection. Also, wifi is much more unreliable than ethernet and not recommended at all, but if you have no other choice… The short version: …

and specifically chapter 3. Set a Static IP with nmcli (optional)

Hope this helps!

Hi, I need some help from you. My hassio seems to have issue with DNS and I can’t install any addon at all. When i check the DNS info with ha dns info, there is 8.8.8.8 and 8.8.4.4 defined under the local sections.

Can you please share your DNS info with me here so that i can confirm if mine are setting correctly?
Thanks

I am having the same issue. I don’t really understand how to set the DNS and it refuses to connect via browser if I set it to 8.8.8.8 and 8.8.4.4

Note this should be done form Settings > System > Network now.
