Hub portal showing error notification

I wasn’t sure where this belonged.

My hub is showing the following message:

Please contact support, cloud connection is unavailable.

Is anyone else seeing this?

I have seen it a couple of times now. Reboot the hub and it goes away.

I got this a while ago…
Logged in to the portal and could see it was connected and I could connect to the hub from there so, I just assumed it was an erroneous message… and a reboot did clear it eventually.
