Ikea Tradfri not working since upgrade to 0.53

I’ve just upgraded to v0.53 of Hass

Now tradfri isn’t working.

I don’t really know where to start, i’ve checked my tradfri.conf file, it’s correct.

I’ve also removed it, and rebooted hass - when I do that I get an option to configure in hass - but that fails and I notice in the terminal window (that is running hass) a timing error (highlighted red) every time I try to configure.

Any advice on how to troubleshoot?

I had a similar problem with weather underground. I had created a sensors.yaml file to organize all the weather sensors. In that file I had a line like " api_key: !secret wunderground_api_key" that pointed to another file. Anything like that in your tradfi.conf file? I really have no clue, but wanted you to know you are not alone.

All sorted now, reboot of tradfri fixed it.

Thanks
