Even after a long wait, the final step is not working. I tried every step nicely and double-checked.

I think some actions are needed on your end, or some of the latest updates may caused this not to work. Please help me to pass this step. Thanks.

Hi Shafi Khaksar,
Thank you for reaching out to us on the Microsoft Q&A forum.

I've provided the Unit 3 repro steps at this link:https://learn.microsoft.com/en-us/answers/questions/2047306/error-when-create-a-linux-virtual-machine-and-inst

If it has been over an hour since completing the prerequisite in Unit 3 – Exercise: Create an Azure Virtual Machine, your VM may have been automatically removed, causing an error in Task 1, Step 2. To avoid this, ensure the prerequisite of creating a virtual machine in Unit 3 is completed within the hour before proceeding. After completing the Unit 3 exercise, move on to the Unit 9 exercise, restart the Cloud Shell, and follow the steps outlined in the document to ensure smooth functionality.

We also tested it on our end and obtained positive results, as shown in the screenshots:

Hello,

Thank you for your time and efforts. I re-implemented carefully all the steps again. Still, the issue persists with the final part.

Error

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

curl: (7) Failed to connect to 13.93.145.66 port 80 after 1 ms: Couldn't connect to server

Hi Shafi Khaksar

Thank you for your patience and for trying the steps again. I understand you are still facing the issue, and I am sorry for the inconvenience.

It seems that perhaps the problem is with the Cloud Shell environment. After the completion of Unit 3 exercise, go directly to Unit 9 and restart your Cloud Shell. This is because sometimes the environment might need refreshing after completing a previous module.

After restarting the Cloud Shell, try running the command az vm list. This will tell you if your VM is still running. Once you confirm your VM is active, follow the steps outlined in the document. This should help resolve the issue.

If you are still having trouble after trying these steps, please let me know. I am here to help you troubleshoot this issue.

Hi Shafi Khaksar,

It seems you are experiencing connection or firewall issues, likely due to using office credentials or being on an office network. Here are some troubleshooting steps:

Check for Firewall Restrictions:

The office network may have firewalls that block outgoing connections to certain ports, including port 80, which is used for HTTP traffic.

Ask your IT department if there are any firewall rules that block access to the public IP address of your web server.

Verify Network Connectivity:

Test if you can access other websites or services from the office network. This test will determine if the issue is only with your web server, or it is a wide network connectivity problem.

Use a Different Network:

Try to view your web server from an alternate network, such as your home network or your public Wi-Fi hotspot. Chances are that the particular network configuration in your offices is the cause of your problem.

Contact IT Support:

If the issue persists despite trying the above steps, contact your office IT support for further assistance. They can investigate any potential firewall or network restrictions that might be causing the connection problem.

Thank you.

With all respect your answer is weird.

I'm MCSE certified, and I don't think reaching the query on the browser is the point! You haven't considered that we're talking about the cloud shell result, not the end-user.

Hi Shafi Khaksar,
Apologies for the confusion. The issue seems to be caused by a glitch in the exercise, which is why you are seeing an error. However, if you refresh the webpage where you copied the IP address, you should still see a successful output. We have provided some troubleshooting steps, and upon retrying on our end, we were able to execute the exercise successfully.

We kindly request you to try running the exercise again and let us know if you face any further issues.
