Late to the party but hopefully this will help.
Same situation for me. I tried everything including disabling the firewall. Then I realized....the machine is not "approved". Once I approved it, everything turned on and started working as normal.
So:
Go to Devices,
search for your device,
right-click,
Approve,
wait and see, or initiate the Machine Policy Eval/Hardware Eval cycles.
This happens because the site setting for Client Approval is either set to Automatically approve computers in trusted domains or Manually approve each computer.
