There was an issue with server maintenance. It’s back up, and usually the cloud will reconnect after awhile without any user intervention. However, you may need to restart the cloud connector (or just restart/reboot openHAB).
My instance is offline since yesterday 9pm. Any new issues here in the meantime?
Since i am not at home the next week, any chance to do something from remote without having ssh tunnel to the openhab instance?
