Any help on this?
Thanks in advance

I guess this is matching your issue https://community.home-assistant.io/t/another-problem-with-ikea-tradfri-and-0-56-autoconf-problem/30864

Thank you for the link but still have the same error: Config flow could not be loaded … :cry:

did you install autoconf via apt and dtlssocket via HA user python environment?
