HomeAssistant + Pi Hole = Interface Web No Access

I cant access homeassistant web interface after install of the Pi hole.

Pi hole: 100% working
Home assistant Interface web (internet): no working
Home assistant Intranet: 100% working

My configuration:
Raspbian Stretch + Pi 3 + Homeassistant + Pi Hole

PiHole shouldn’t affect things coming from the outside in but instead from the inside out. Have you tried, externally, to make sure your address is current and up to date? A simple ping from outside your network should let you know.

Returned on working.
But i didnt do nothing.

You should assign external port 443 if you are using ssl , and change the base_url to mydomain.duckdns.org:443

I don’t think that Pihole has anything to do with it, as it is running on port 80 (http) only. (unless you have setup ssl for pihole of course)

Thanks, my friend.
