HA Yllow zigbee not working

HA yellow user and suddenly the zigbee integration isn’t working. We had a power cut for about 30 seconds but not sure if the issue was there before. I’ve tried reconfiguring but still it’s not loading. Tried a reboot, unplugged and plugged back in but still nothing. Does anyone have any suggestions? Thanks.

It gets worse. I tried setting it up again and it fails every time

Are you sure the skyconnect is on that port? It is preferred to use the serial by id because a reboot may cause the coordinator to be detected at a different port number. Check the hardware page in the settings.
