Error Home Assistant Companion iOS - Raspberry Pi 3 - Static IP - Docker

Mobile Apps Home Assistant Companion for Apple
1

I am running home assistant on

  • Raspberry Pi 3 Model B Rev 1.2
  • Raspbian GNU/Linux 10 (buster).

I have set a static IP address (by editing /etc/dhcpcd.conf). I am running Home Assistant in Docker.
Docker version: 19.03.8
Docker image: homeassistant/raspberrypi3-homeassistant:stable

I am able to open home assistant in the webbrowser on a different device.

When try to open Home Assistant Companion and I click continue on the start screen, the app closes automatically.
