I completed the steps correctly as you mentioned in the task but still the traffic didn’t go through load balancer to virtual machine.

Kindly help me to solve this challenge If you want more information about the problem I’m ready to provide the details. Thanks!
I worked through this one and the LB’s public IP was accessible; I got the standard nginx default page.
The one thing I don’t see in your output is a NSG for port 80 on the VM’s default NSG. You’d need to do this for the LB to be able to get through to the VM.
The health probe is in up status.
I got the lab to work just using the task description, but you may also want to look at this solution, to make sure that you’re hitting all of the required items.
Thank you for your response!
I completed the challenge based on the solution you shared. And I found the issue in the VM NSG I gave 80 in source port range. But in the solution that suggested to use all port ranges. After change to all traffic it worked.
