Hello Azure8010
Welcome to Microsoft Q&A Platform, thanks for posting your query here.
There could be couple of reasons for this error. The first one is outdated firmware version and the other one is that you are running WAC on an un-supported OS. Make sure WAC is installed on Windows 10 and above (client) or Windows 2016 or above (Server).
Make sure the NIC firmware and drivers are updated and matched across the systems.
Also, if you are in the cluster creation wizard, I have found that if you don’t completely exit and start the cluster creation over, it won’t pick up any changes that may have been made to the drivers (such as if they are updated).
Hope this helps.
