Openhab cloud connector binding reinstallation issue

It seems to me after I reboot my local openhab server, sometimes I need to redo the openahb cloud connector binding as below.

1 IP:8080 -> paper UI -> addons -> misc -> openhab cloud connector -> install
2 paper UI -> configuration -> service -> openhab cloud -> confiugre -> URL -> my openhab cloud server domain here

Is it something normal or I can do something to avoid this?
Can some expert shed some light?

Are you using a mix of installation of add-ons through PaperUI and addons.cfg? If so what ever is in addons.cfg will take precedence meaning that any add-on you install through PaperUI will get uninstalled automatically.

Beyond that, I’ve no ideas.
