I have 2 web servers (IIS) Virtual machines that are behind a azure internal load balancer (10.10.120.15). These 2 webserver host 1 common sites in both the server (eg. https://pp-xx-app.abc.net)

A record created pointing to internal load balance with same name as pp-xx-app.abc.net - 10.10.120.15

I have created load balancing rule on TCP/443 port to the backend web servers.

Also I have created TCP/443 port in the health probe.

On each webservers, we have these 1 sites common (eg. https://pp-xx-app.abc.net) with https binding to 443 with SSL certificate configured.

All looks good but when i try to access https://pp-xx-app.abc.net say can't reach this site. how to fix this issue ?

    @Amsaraj, Rajkumar

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

    I see you have created a record pointing https://pp-xx-app.abc.net to the internal IP of the ILB, however, this was not working

    Before testing this with ILB, I suggested we

    • Confirm that the VMs are working properly
    • Instead of pointing the site to the ILB's private IP,
      • Point it to the IP of the VMs
        • And make sure these individual VMs respond to the HTTPS requests
          • Share the results for directly accessing the VMs

    Meanwhile, you informed that Floating IP was enabled and this in turn was causing the issue.

    Once disabled, you confirmed that the site works perfectly.

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

    Thanks,

    Kapil
