Integration now Unavailable

[nodinosaur]

For some reason my Dyson Pure Hot+Cold Link is now shows as Unavailable.

There is no error code, or any form of guidance on how to fix the problem

I cannot pin-point when it happened but the only change has been an upgrade to the latest version of Home Assistant.

I have tried restarting, no change

I have deleted the integration and tried to set it up again using Setup using WiFi information but I now get Failed to find the device using discovery

Is there anyway to set this up again?

Thanks
