I installed HASS on a raspberrypi using hassbian. Now I’m trying to setup Let’s Encrypt for remote access, but for some reason it can resolve the hostname of the certbot (e.g. dl.eff.org). And it can’t resolve any website IP address.
If I enter ping -c 1 220.127.116.11 it works, but ping -c 1 www.google.com does not.
I added dns-nameservers 18.104.22.168 22.214.171.124 to the /etc/network/interfaces but no luck.
