Hello daffda,
Thank you for reaching out to us on the Microsoft Q&A forum.
Task 1: Access your web server. Step 1 will take the IP address of the VM you created in an earlier lesson (Exercise - Create an Azure Virtual Machine) and store it as a variable. If it's been more than an hour, that sandbox and all related resources will have been removed, and the variable won't be created correctly.
- Go back to Exercise - Create an Azure Virtual Machine.
- Complete the module to create the VM.
- Try Exercise - Configure network access again. This time the variable in Task 1, step 1, should be set correctly, and you should see the correct response after running curl on step 2.
