along with https://github.com/openshift/cluster-network-operator/pull/604 should fully fix current windows networking issues

This is isolated to the windows gateway code... and that is already broken by this, so it can get no worse.  So moving back to 4.4.0.

Just have a discuss with sgao who setup the windows worker cluster

The windows worker is using the old veresion hybird-overly.exe from https://github.com/openshift/windows-machine-config-bootstrapper/releases/tag/v4.4.3-alpha

maybe it caused the pod cannot be communicated between windows and linux pod
