Windows Cluster Communication Issues

failoverfailovercluster

When I first created a windows cluster (with a Cloud Witness if it matters), everything went smoothly. Then something went wrong with the communication and I had to destroy the cluster.

Now, when I try to create a new cluster and add a second node, I get a message the following message:

Cluster service on node jupiter2 did not reach the running state. The
error code is 0x5b4. For more information check the cluster log and
the system event log from node jupiter2. This operation returned
because the timeout period expired.

It then rolls it back. This happens even when I create two brand new servers with the firewalls turned off. I have even created two servers in the same hyper-v host with an internal network to eliminate the possibility of my switch interfering. Same issue.

I have tried all of the basic troubleshooting ideas that I can think of – since the issue still occurs with two brand new machines it would seem like there is a GPO or something else in active directory causing the issue – but I'm out of ideas.

What could be causing this issue?

This was caused by having DOS protection turned on in my Ubiquiti EdgeSwitch. Now that it's disabled, it is all working.
