    Hi @Naveen Neerukattu ,

    there are different things you could check/test.:

    • Are you able to connect to the VM via HTTPS without using the Load Balancer (verify the IIS has a binding for HTTPS)
    • Are you using trusted certificates for HTTPS?
    • Please try to use HTTP Port 80 for the Health Probe and HTTPS/443 on the Load Balancer Rule.


    (If the reply was helpful please don't forget to upvote and/or accept as answer, thank you)
