Azurev VM doesn't connect to internet

Hello, I have a Windows 11 VM in Azure. When I try to go to Google or any website it just says time out. What can I do to get internet working?

@leli eee ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you are facing issues with Internet connectivity in your Azure VM.

The best way to check if NSG is blocking traffic or not is by using IP flow verify overview

Or you can use NSG diagnostics as well How to test is described here : Check security rules applied to a virtual machine traffic

And share the results of the test.

Cheers,

Kapil

most of the time it is related with NSG issues

Check the NSG associated with your VM's subnet, ensuring the following outbound security rules exist:

Allow port 80 (HTTP)

Allow port 443 (HTTPS)

Allow DNS traffic (port 53 UDP and TCP)

In addition

Ensure your VM's subnet has a valid default gateway configured for routing traffic outside of the Azure Virtual Network.

Verify that the VM has appropriate DNS servers configured that can resolve internet domain names. You can use Azure's default DNS or reliable public options like 8.8.8.8 or 1.1.1.1

Also here is the official troubleshooting document by Microsoft
