IKEA Trådfri integration started fail

Third party integrations

After reboot of homeassistant my IKEA Trådfri integration suddenly started failing.

It may be related to an update on my controller but im not sure. Im using first gen controller/hub.

Currently running these versions:

Home Assistant 2023.5.2
Supervisor 2023.06.1
Operating System 10.1
Frontend 20230503.3 - latest

TRÅDFRI Gateway uses version 1.20.65 which seems to be relased recently:

Problem solved.

Restarted tradfri gateway then homeassistant (again).
