HASS failures all over

I am new to HASS.

In the process of migrating from a range of Home Automation hubs to HASS.

Trying to consolidate.

I am running the latest version of HASS in a VM.

Today the Node Red HASS nodes have all gone grey with unknown as has the HASs config node.

Also Govee, HomeKit device and Nanoleaf have all failed.”Failed setup, will retry”

So the Node Red no longs works with HASS devices.

Backed up Node Red Flows. I have uninstalled Node Red integration, full reboot, in order to get it to get the HASS integration re-installed.

Unfortunately upon re-install of node Red, another full reboot of Vm

Node red is reinstalled without HASS and interestingly with the flows as well, so doubting the uninstall integration is actually uninstalling it.

Anyone any ideas on how to restore Node Red, HomeKit device and Nanoleaf?

Made some progress

After some research found the module to add back

node-red-contrib-home-assistant-websocket

And at first glance seems to have enabled the missing nodes/flows

Will test and if working will move onto the other integrations that died.
