Adguard -> 502 bad getway

Installation Home Assistant OS
1

i just installed “adguard home v1.0.1” from Hass.io.
Config window has:
{
“ssl”: true,
“certfile”: “fullchain.pem”,
“keyfile”: “privkey.pem”
}

i left that config and network window as is.
clicked on start, and Open web UI to get error of 502: Bad Gateway
http://192.168.1.233:8123/hassio/ingress/a0d7b954_adguard

do i have to fill in anything in the config or network?
i changed SSL to false because i am not using https and that failed too

I had that too. Turns out you have to have some patience for the add-on to start up:)

this is what i see in Hassio log:
2019/05/07 14:09:46 [info] Creating the UDP server socket

My guess is you already have another DNS server running (which defaults to Port 53). Maybe pihole?

very strange. there is no pihole in the house.
but i am tempted to install pihole from hass.io next if adguard does not work

Do you by any chance run on an Ubuntu box? If so, check out this comment:

i followed the link and the page for adguard loads up now! :smiley:
the first solution didnt work for my ubuntu but after following more suggestions, this works for me…
sudo nano /etc/resolv.conf
change to my verizon’s router ip of 192.168.1.1

sudo systemctl disable systemd-resolved.service
then sudo reboot.

thank you everyone!

I was having the same problem. It turns out you can not run DNSMasq and AdGuard at the same time.

Thank you very much my friend! That was exactly my problem! DNS mask stopped and it worked! :slight_smile:
