SQL Server Availability Group - Listener configuration problem
In order for the IP address to be brought online, three requirements must be met (among others, but these are the most relevant to this error):


At least on of the listener IP addresses must be in the same subnet as one of the cluster networks.
The cluster network that is in the same subnet as the listener IP address must be configured as a public network (will add more details in a few minutes).
The IP address must not be in use on the network.


You can view and configure the cluster networks in Failover Cluster Manager.  Expand the cluster and select the Networks node to see the networks.  Right-click on a network and select properties.  Ensure that "Allow clients to connect through this network" is enabled on all networks that are used by listener IP addresses.

If you need further help, please add more detail to the question regarding the network and IP configuration of the nodes and the listener.  The only useful information in your question at this point is the error message, so that's all I have to go on.
