Can't resolve hostnames on Hass.io

Installation Home Assistant OS
1

I can’t get any hostnames on my network to resolve to their IP from my Hass.io install. I’ve found a few topics including Name resolution problem since 0.97.2 and an issue on GitHub. Both offer solutions which I’ve tried and detailed out below. But still, I can’t resolve any hostname. When I try to resolve a hostname on my laptop or phone, it works perfectly.

My router is OpenWRT and is running dnsmasq and automatically resolves local hostnames with a local TLD.

What I’ve done so far

~ hassio dns options --servers dns://192.168.0.1

~ hassio dns info
host: 172.30.32.3
latest_version: "1"
locals:
- dns://8.8.8.8
- dns://8.8.4.4
- dns://fdb5:9091:4587::1
servers:
- dns://192.168.0.1
version: "1"

~ ping firetv-livingroom.lan
ping: bad address 'firetv-livingroom.lan'

➜  ~ ping 192.168.0.243

I’m on Hass.io supervisor 193, HassOS 2.12 and HomeAssitant 0.103.5.

Don’t forget the hassio dns restart after you changed the hassio dns options.

I’ve run hassio dns restart and restarted the entire HomeAssistant container but still no luck.
