I have tried to find a solution for this by following the instructions in various posts.
I don´t know how this can be solved? I hope someone has an idea how to fix this?

configuration.yaml

tradfri:

host: ip-address

api_key: security code

I've had the same problem yesterday.

The solution for me was to manually install DTLSSocket. But this worked only, when I've installed Cython.

sudo pip3 install Cython
sudo pip3 install DTLSSocket

Make sure that this will be done in the same terminal-window, where you start the homeassistant. This was another mistake I've made.

Always start homeassistant with the options -v --debug. This writes informations into the logfile and you will see what was the problem.

I've got the same problem, only on my raspberry pi B
Hassio has no access to pip3 so unable to solve the issue like you suggest

Thank you for the reply and suggestions.

I could not install to /srv/homeassistant/bin/ folder Cython because it is already installed elsewhere.

I´m using VirtualEnv for Homeassistant and also using Homebridge on PI3. Therefore there are some owner conflicts with /usr/.cache/pip ? Should it be /home/homeassistant/pip or /srv/homeassistant/bin/

I´m also using older version of AppleTV so it wouldnt work anyway. But same kind of issue installing dependency.

Does this mean that I need to reinstall homebridge and homeassistant? Currently I have no need for homebridge and I installed it just to experience how it works. Homeassistant is the one I would use.

Here is home-assistant.log information:

I made an fresh installation of Hass.io and now using latest 0.57.1 and now AppleTV works, Tradfri works. Great! Awesome update.
