Internal load balancer not working

Hi all,

I am trying to setup an internal Load Balancer in Azure to support the high availability ADFS servers.

I had a Resource group, virtual network and subnet already created from before.

I have created the Load Balancer (via Azure Portal and then also via PowerShell), assigned it an internal IP, then added backed pools, health probes and the load balancing rule.

I didn't create the inbound NAT rules because I don't see it necessary for my scenario.

When I try to access the ADFS sign-in page, it doesn't show. I also cannot ping the LB IP address. When I try to access the ADFS sign-in page on one the VMs it is working ok.

Can anyone help me what I am doing wrong?

Thanks in advance.
