It’s been a while since I originally setup HACS and the integrations I use within it, but I have gone back into it recently and am seeing “Unknown Error” displayed on the screen when I try to click on any of the Integrations I have installed (SensorPush, EcoWitt, Hubitat, Nest, etc). I also do not appear to be able to update either Hubitat or Nest, which are showing as having updates available. Not sure if that is related.
I have seen posts about SSL with respect to my EcoWitt integration, but I am only connecting through HTTP. Again, not sure if that is related.
The main reason I was getting into HACS was to try and uninstall the EcoWitt integration and start using the recently added built-in one.
