I am trying to build a SQL Server AlwaysOn Availability Group with 2 nodes in Azure. I have created 2 SQL Server VMs and Managed to create a Cluster with both Nodes as members of that cluster.
I have followed the steps in this Article of building the Windows Clusters https://docs.microsoft.com/en-us/azure/azure-sql/virtual-machines/windows/availability-group-manually-configure-tutorial
with 1 significant change, I used powershell to create the cluster.
New-Cluster -Name SQLClusterName -Node ("SQLNode1","SQLNode2") –StaticAddress 172.100.10.100 -NoStorage -ManagementPointNetworkType Singleton
Because, if I used Failover Cluster Manager to build the cluster it did not created Cluster Core Resources and I did not gave me the option to select an IP for the cluster.
Anyway, once the cluster has been configured, I tried to configure AlwaysOn Availability Group, but the wizard fails to create Always on Availability Group, complains about it cannot connect to the Cluster.
I went on both Nodes and what I have realised is that I can ping to the Cluster Name or IP and get a response only from the Owner Node. From the cluster Non-owner node I could not ping the cluster name or IP. If I failover the cluster to the 2nd node the I ping behaviour will be contra versa.
Has everyone else experienced this issue? Is so, how you managed to resolve it? Any help or a pointer in the right direction is much appreciated. Thanks in advance.

I managed to fix this by enabling HA ports in the Azure Load Balancer (standard Load Balancer). That seems to have fixed the issue.
By the way I have SQL Server 2019 Enterprise on Windows Server 2019.
Set the following Load Balancing rule in the Azure Load Balancer for WFCS.

The article does not talk about HA ports because it is a Standard Azure Load Balancer feature and the article was written using a Basic Azure Load Balancer.
