Solar PV production charts are missing from Energy Dashboard

All the solar PV production charts have gone missing in my Energy Dashboard. Happened a day or so ago.

The production totals are appearing as normal in the energy flow card at the top right but the main production chart at the bottom shows nothing. Also missing is the PV forecast data.

This is what I would normally see (a screen capture taken a couple of days ago):

It’s the same for day, week, month and year views. The totals appear in the energy flow card but the Solar Production chart is blank. So the data is there.

The sensors appear in the energy dashboard configuration and they are reporting OK when I check them with the Developer States tool.

I’ve since restarted HA but it makes no difference.

Any clues on what’s happened / how to fix?

Thanks

Bump. Has no one else had this issue or have any suggestions?

Took a couple of restarts but the charts are now back in their rightful place.

OMG. I was just about to post about this exact same thing happening to my HA.

More restarts it is, then!

Repeated restarts for the win…

Did you see if there were any errors in your logs about forecast.solar? I believe that API has been glitchy lately, I wonder if the forecast failing is causing the whole card to break.
