    Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

    I understand that you are facing issues while adding a VM to the backend Pool of a Load Balancer.

    Based on the screenshot,

    I am assuming that the Load Balancer is of basic SKU.

    And there is an existing VM already associated with this Load Balancer and the new VM you are trying to add is not in the same availability set as the existing one.

    This is an expected behavior with Basic SKU load balancer.

    Refer : SKU Comparison

    To mitigate this,

    • You can either use a Standard SKU Load Balancer
    • or Create VMs in the same availability set as the existing one

    Kindly let us know if the above helps or you need further assistance on this issue.
