Fritzbox host resolution / connection on 1012 port [sensor.fritzbox_callmonitor]

Hi all,
I have a network problem trying to connect to my local FRITZ 7390
FRITZ!OS: 06.85

[homeassistant.components.sensor.fritzbox_callmonitor] Cannot connect to on port 1012: [Errno 113]

trying with:

  - platform: fritzbox_callmonitor

in the last case the error is

Cannot connect to on port 1012: [Errno -2] Name does not resolve

but always the same results… no connection to the server

Home Assistant version is 0.84.6 and is running on docker.
My docker containers are:

CONTAINER ID        IMAGE                                      COMMAND                  CREATED             STATUS              PORTS                                    NAMES

Call-monitor is activated on the FB (#965) and tested with JFRITZ on my laptop on the same network.
From the host system i’m able to connect to the server with a telnet

pi@raspberrypi:~ $ telnet 1012

Escape character is ‘^]’.

thanks in advance for the help


Docker containers run in their own network, so maybe the Fritzbox is refusing requests from it.

Try running the HA container with —net=host

Thanks for your reply. Just a question – cause I’m a newbie – is there a way to keep this configuration also on the restart of the host system?

It usually is. I am not using HASS.IO, but just a dedicated Home Assistant container and my commandline looks like this:

docker run -d -u $(id -u):$(id -g) \
  --name=hass --net=host --restart=always \
  -v $PWD/home-assistant:/config \
  -v /etc/localtime:/etc/localtime:ro \

thanks again it’s working!!!
