Hass.io error while connecting to IKEA Tradfri gateway

lucky you… :frowning:
deleted file in config folder… no folder in deps… and still a no go

tradfri gateway fw version you guys are using?
1.2.42 here

Same here. gateway firmware version 1.2.42 .
I’m able to use the Tradfri component on a development board with Docker on CentOS, that has same hassio version (0.57.2).

try factory reset on tradfri gateway…
that will issue a new key
