Limitless LED not working - Cloudserver Problem?

Since Yesterday my Limitless LED won’t responde to commands from HASS.
The strange thing is I didn’t change anything.
Throught the app of Mi-light I can still control the lights, but not from Home Assistant.

Anybody having same behavior? And maybe a solution?
thank you!

No mine are working fine. They don’t require a server for local control. Did the IP address of the hub change perhaps?

After Some checks yesterday I think the solution is found. In my UniFi router I have the option to automatically mage the network. But what happens is that he shuts down mesh networks. I think the Mi-Light might be blocked that way. After disabling this option the lights work again. Thank you for your input and feedback!
