First do a API GET in Postman to get the compute manager id:

As you can see the compute manager is registered and up, why is it not showing up in the UI?

Login with the admin user by SSH, and run the following command.
start search resync inventory
Wait a few seconds and refresh the UI, now the Compute Manager is back!
