2019-05-29 22:43:57.037 [INFO ] [io.openhabcloud.internal.CloudClient] - Disconnected from the openHAB Cloud service (UUID = b57cf842-13f2-4f6a-b3a9-0115534ceecb, base URL = http://localhost:8080)

But at the same time reports that the connection is online.

But the localhost connection works.

The following actions done without no success

  1. Rebooted Openhabian
  2. Uninstalled cloud connector, reinstalled and configured again
  3. Reconfigured UUID and password at

Seems everyone is having issues with OH cloud. There is another thread running parallel to this one.
