[puddly]

The exception means that a device is unreachable because the coordinator firmware can't figure out how to route to it. It's not really something ZHA can fix.

Please attach diagnostics information for ZHA.

Could it be due to old Z-Stack ? Z-Stack 20210708 On the other hand it works with HA 2025.3.3

[boguslawb]

I upgraded Z-Stack then upgraded HA and then re-added device. This fixed the problem. You may close this issue
