Dark Sky not working

I have had the Dark Sky sensor up and running for a while now. Yesterday I had to restart my physical server and now the Dark Sky sensor has stopped working. I didn’t change anything, all I did was restart the physical device.

I can’t seem to see any logs either to be able to tell what’s gone wrong. I’ve tried resetting my API key, rebooting HA, adding additional config variables (longitude and latitude).

Has anyone else had any similar problems?
