Cluster Network Communication for Cluster Aware Updating
As you know, Zero Downtime and small maintenance windows don't often come together well.
We would like to leverage Cluster Aware Updating to patch our HA clusters. The problem is that the Cluster Network does not allow communication.
We would like to see the network traffic enabled for the Cluster IP so that we may let automation safely patch and fail over.

Recently we had issue with Windows Cluster and we could see event ID 1135. However, we are in Azure and support team informed there was no network or hardware issue. Event viewer and other logs are not pointing to any concrete root cause. I suggest to improve and add feature for better Telemetry. Please also check if this is a bug in Windows 2012 R2 because we did not face this issue in 2016. Cluster issue occurred on 5 different servers which are on 2012 R2.
