Hi Team,
I have created a Static Public Load balancer with Backed 2 vms.
The problem is the backend vms are not able to fetch the Public Ip address of the Load balancer.
Backend vms are having Private IPs but Public Ip showing as Empty.
Need help

    Hi @Naveen Neerukattu
    Can you post screenshots of the structure? Is your load balance standard?
    Make sure you are not using internal load balance, try to create a standard public ip and attach your vm's NIC.

    I have load balance scenarios with public ip in vm, below a print of a basic load balance with ip in VM

    Hi @Naveen Neerukattu ,

    Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
    I understand that you are not able to see the Public IP address on the VM via Portal.

    I was scoping the following,

    • Are you using a Standard Public Load Balancer or a Basic one?
    • Have you configured the backend Pool with NIC or IP-Based?
    • Can you please make sure the VMs are in a running state while you check for Public IP?

    Post which, you have confirmed the issue has been resolved.
