Fuel Not discovering nodes after successful pxe boot

Hey all,
I'm using fuel 9 to deploy openstack.
The slave nodes pxe boot off the fuel controller and install the bootstrap image fine,
They can even ping to the internet routing throguht the fuel master .
And the syslogs are being sent to the master as well.
But the fuel master isn't discovering the nodes

Only thing that looks like an error is this

agent.log on slave node:
