Upnp error: Operation not permitted

Configuration
1

Hi,

Since a few weeks my HA logs are overflowing with these errors. Also my rpi4 is crashing every 1 or 2 days. I have HA running in docker next to mqtt and zigbee2mqtt. Everything was working file until a few weeks ago. I think the crashing and the errors is the logs might be related. Does anyone have any clue what the error might mean? The Operation Not Permitted error didn’t gave me any results on Google or the forums.

Thanks!

UPnP is a service to automatically open or close port forwarding in routers.
This might be your internet router or your virtual router if you use virtualization layers, like do let, proxmox, virtualPC and the likes.
