Issue with Azure platform communication (168.63.129.16)

Having an issue communicating to the Azure platform IP 168.63.129.16. When I do a fw unloadlocal the errors on the console stop and the VM in Azure Portal stops reporting that the Azure agent is not working. However, I tried the following in my firewall policy and none solved the issue:

  1. Allow HTTP, DNS and TCP\32526 from cluster object to 168.63.129.16.
  2. Bypass HTTPS inspection (shouldn't have an effect since communication to Azure platform is HTTP)
  3. Applied new policy package with no Threat Prevention.

Edit: The default routes on the gateway VMs have not been changed.

Some errors seen on the command line:
