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

Comment 2 Ben Bennett 2020-04-24 17:49:34 UTC

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.

Comment 8 zhaozhanqi 2020-04-29 11:15:30 UTC

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
