Zigbee Mesh Map Problem

I’ve installed zha_map and the zha-network-visualisation-card, and am getting a partial map displayed.

The entities are there with the end devices as circles and my coordinator as a rectangle, but there are no linking lines. The rectangle for the coordinator shows ‘offline’.

The coordinator must in fact be online as my zigbee devices all work OK.

Does anyone have any ideas, please?
