Dont really know how it happened, but Home Assistant takes long to load and Supervisor and other addons (Deconz, Configurator) are blank.
I dont get any errors. Looked in the log but cant really find anything. Seems to be related to duckdns, when I remove the http settings in configuration.yaml and go to the ip instead it works.
Tried restart multiple times, tried downgrading Supervisor.
Does anyone have any suggestions?
I have the same issue. Did you solve it?
