Website is inaccessible using NLB cluster IP/DNS while same works fine with individual IP/Hostname

I have created Microsoft Network Load Balancer for one of my Web application which is hosted on IIS. I add both hosts in NLB cluster, it is successful. I have made cluster entry entry in DNS and resolving properly. I don't find any  misconfiguration but still If access website using cluster name or IP then it is not accessible while from individual IP of  hosts, it works fine. Where is gap help me pls? I am trying to access internally.

Check the website bindings to make sure they are not restricting traffic to a single IP address.

How can I check it, can you please suggest steps?

Finally I fixed it my self. If you create NLB in unicast mode, only one node will be active, this is default configuration. To make all nodes active, need to do change in registry. So I configure NLB in Multicast mode, it is working perfect.
