Trouble Creating AG Listener: The WSFC Cluster could not bring the Network Name resource
I was able to resolve this issue in my lab.

I setup an Availability Group between two virtual machines in my lab.  I was not able to add the listener as part of the initial setup and also couldn't add it afterwards.

Each server had two network adapters on different sub-nets.  When I disabled the 2nd network adapter on each server, I was able to add the listener successfully. I then re-enabled the 2nd network adapters successfully with no adverse effect on the listener.
