Smartthing water sensors all went offline (September 2023)

All of my Smartthings water sensors went off line at same time as well as my Sylvania plugs this morning. I have Aerotec V3 hub. All has been working fine. Hub shows connected. It comes up server off line. Unfortunately this is a rental house in another state and I can not physically check but I do know lights inside house were left on. I can see them by camera. Any thoughts or ideas.
Is this a Zigbee issue? Has a recent update caused problems?
Thanks for any feedback.

Update;
Was able to remotely reboot hub and all Zigbee device came back online. Outlet switches became operational and so far no issues. Not sure why they all went off line at the same time. There was no issue with internet.
