Your openHAB is not online while I can access my local openhab server locally.

I guess reboot local openhab server may bring it online again.

Thank you.

Your myopenhab.org connection is not working. Has it ever shown as online on myopenhab.org? If so does a reboot fix it? Are there any errors printed in the logs?

It works by reboot. Nothing special printed out.
Just connect cloud server.
