I have 2 VMs behind a load balancer on Azure. I have enabled HTTPS connection for the Websites i have deployed in those VMs using self signed ssl certificate. When I connect to that VM directly via IP I see the certificate loaded, but when i try to connect through load balancer over HTTPS, I get a page which specified "Your connection is not private" (as it is self signed certificate) and in Advanced i click on "proceed to site". For VMs it works, but when i use load balancer IP it will load the same page again and again specifying the same error. I couldn't find much material for implementing HTTPS as well. i implemented based on my understanding of Azure load balancer.

Also can i achieve HTTPS using load balancer or do i need to implement Application Gateway?

Privacy Error:

Error in Browser


You can use the Azure CLI to create an application gateway with a certificate for SSL termination that uses a virtual machine scale set for backend servers. In this example, the scale set contains two virtual machine instances that are added to the default backend pool of the application gateway.


  • Does this mean i cannot create using load balancer? – V Ganesh Apr 5 '19 at 4:47
  • Azure Load Balancer is a layer 4 service, it works with all UDP and TCP protocols . App Gateway is a Layer 7 service that can provide SSL offload (this can't be done at layer 4). See our docs for details on the different load balancing services in Azure. docs.microsoft.com/en-us/azure/traffic-manager/… – Ken W MSFT Apr 5 '19 at 13:24
  • Thanks. I have one last doubt. In my current implementation i have installed self signed certificate on my VMs. In load balancer i configured port 443 having HTTPS health Probe. I am getting Privacy Error as it is self signed certificate. If i have a proper certificate signed by certificate authority, wont it work? – V Ganesh Apr 8 '19 at 5:23
