| MELCloud Home | Not working Cloud | Invalid email or password after provider outage; app also affectedSaved copyThe problem Hello, I don't have a custom Melcloud integration, but rather the one that can be selected when adding a device in Home Assistant, "Melcloud Home." I've had this problem since this morning; I'm getting an error message on Home Assistant Core. I can no longer log in to Home Assistant, even though it works fine in the Melcloud Home app. I removed the Melcloud Home integration from Home Assistant and then reinstalled it, changing my password. The problem persists. I still can't log in. Could you please look into this?
