Hi Nida ul Zafar,

We apologize for the inconvenience. Based on my understanding of the issue, you're practicing the following Learning Path exercise:

Section: Describe Azure architecture and services

Module: Describe Azure compute and networking Azure

Unit 3: Exercise - Create an Azure Virtual Machine

Unit 9: Exercise -configure network access.

You could have a Network Security Group preventing inbound traffic on port 80, or the Virtual Machine itself could have a configuration issue where it's not listening on that port.

if the answer is helpful, we kindly request you to consider marking as accept answer, as this action enhances the visibility of feedback for other members in the Microsoft Q&A community. Your contribution is greatly appreciated in improving Microsoft Q&A!

Hi Nida ul Zafar,

I believe you are referring to the following exercise:

https://learn.microsoft.com/en-us/training/modules/describe-azure-compute-networking-services/9-exercise-configure-network-access

Please correct me if you are referring to a different exercise.

Was the sandbox still active when you copy/pasted the above command into the cloud shell? If the previous sandbox expired, you may receive an error saying it cannot find the resource group.

It is intended for you to activate a new sandbox and complete all of the tasks in Unit 3 (earlier exercise) and Unit 9 (exercise you are referring to) in less than 1 hour. The sandbox expires after an hour and all the resources (including the learn-xxxxxx resource group) are deleted automatically.

If you scroll back up to the top of the exercise you can see the remaining time before the sandbox expires.

Please go back to Unit 3 Exercise, activate a new sandbox, perform all of the tasks, jump to Unit 9 Exercise, perform all of the tasks, and then reply back with your results.

You could have a Network Security Group preventing inbound traffic on port 80, or the Virtual Machine itself could have a configuration issue where it's not listening on that port.

If the answer is helpful, we kindly request you to consider marking as "Upvote" as this action enhances the visibility of feedback for other members in the Microsoft Q&A community. Your contribution is greatly appreciated in improving Microsoft Q&A!

Thanks.

Hello there!

I have the same issue, although the VM is running and the network security group rule allows inbound traffic on port 80:

Name Priority Port Access

default-allow-ssh 1000 22 Allow

allow-http 100 80 Allow

echo $IPADDRESS

13.64.176.90

curl --connect-timeout 5 http://$IPADDRESS

curl: (7) Failed to connect to 13.64.176.90 port 80 after 144 ms: Couldn't connect to server

Any advice?

Thanks:)

So, in addition to my previous comment, the problem was that the home page was not set, via the previous task install Nginx Unit 3 exercise:

After running the script, the home page was set and the server was successfully reached:

curl --connect-timeout 5 http://$IPADDRESS

<html><body><h2>Welcome to Azure! My name is my-vm.</h2></body></html>
