I get the following error and can’t find the problem. Maybe someone who knows what to do?

Try disabling Discovery and restart the service to see if the error disappears.

Maybe if you could tell us a little more about your install it may help.

Well the install is on an Raspberry Pi 3+.
Just started to use home assistent.
Installed a Philips Hue bridge and the Ikea Trafdri hub. Sonos, ChromeCast, Home mini.
Some plug-ins like hacs, postnl, afvalwijzer. Thats about it. Waiting for the rfx receiver to install.

Did disabling Discovery, but the error still exists.
