Question

Network Watcher - Connection Troubleshooting Does not run

Micah Castorina 0

Connection troubleshooting has not been working for two weeks across multiple tenants I have access to. When attempting to run it, it attempts to install network watcher, even if the extension is already installed, and says it can't deploy network watcher. Since I have more than one customer with the exact same issue, this must be an Azure problem. The VM's shouldn't be attempting to install the extension when it's already installed.

Hi @micah castorina

We understand that you are facing an issue with network watch connection troubleshooting.

Please verify the following steps you can try to troubleshoot this issue:

Firstly, check if the Network Watcher agent VM extension is indeed installed on the virtual machines you're trying to troubleshoot. You can do this via the Azure Portal by navigating to the VM -> Extensions + applications.
Can you confirm that the Network Watcher agent extension is the latest version?

Ensure the Network Watcher extension is correctly installed and up to date:

The latest version of the Network Watcher extension is 1.4.3614.3.

Run the following command from an Azure CLI prompt:
```
  az vm get-instance-view --resource-group  "SampleRG" --name "Sample-VM"
```
Check the typeHandlerVersion field for the installed version.
Refer: https://learn.microsoft.com/en-us/azure/network-watcher/network-watcher-agent-update?tabs=windows

3.Make sure that Network Watcher is enabled in the region of your virtual machine. You can enable it through the Azure Portal as well. Also confirm if other regions doesn't have any issues.

Refer: https://learn.microsoft.com/en-us/azure/network-watcher/network-watcher-create?tabs=portal

4.Have you tried running the connection troubleshoot from different VMs or are they all in the same region?

Kindly confirm the above details to investigate further.
