Apple Configurator 2, not working with macOS Big Sur

Hello,

I work within a school in which looks after the deployment of over 1000 iPad devices.

We have recently updated the macairs to Big Sur, and with doing so we can no longer restore/wipe the iPads with Apple Configurator 2, and constantly getting an network error.

Image has been attached, we have checked our filtering system, which isnt blocking anything when trying to restore the iPad.

If anyone has any ideas how to get this to work, this would be great.

Regards

Chris.
