Hue bulbs appear offline

I have dozens of Philips Hue bulbs that have been installed in my home for several years. SmartThings recently has started indicating that they are all offline. At the same time the automations that control these bulbs still work.

Does anybody know what’s going on?


Did you ever manage to sort this out. I am having the same issue. Its driving me mad.

No unfortunately I am still having the same problem.
