Azure Machine Learning Compute Instance Access Error with Private Network

Question

Following error displayed when I selected notebooks on AML workspace:

Error: User does not have access to this compute instance. Please check if this compute instance is assigned to you and you have access to the workspace. Additionally, verify that you are on the correct network to access this compute instance.

My workspace is on a private network, and I am using a VPN gateway to access the AML workspace.

If I change the network to public, the error is not displayed.

How can I fix the problem while keeping a private network?

Additional information:

• The error is also displayed when accessing JupyterLab.
• I do not use CustomDNS Server

Answer 1

@Takayoshi Enomoto Thanks for the question. Here is the document for troubleshooting guide. If you’re using a private network, make sure that your network configuration allows access to the compute instance. This includes checking your DNS configuration, browser configuration, and proxy configuration. If you’re using a VPN, make sure that the VPN is correctly configured to allow access to the compute instance.

I resolved by following steps.

1. Get services endpoint_uri by following azure cli command.
   $ az ml compute show -g <resoucegroup name> -w <azuremachinelearning name> -n <compute instance name>
2. Get workspace IP Address by refer to private DNS zone on azure portal.
3. Add following line to "C:\Windows\System32\drivers\etc\hosts" on local PC.
   <workspace IP Address> <common part of endpoint_uri>
ex. 10.0.0.11 ml-instance-001.japaneast.instances.azureml.ms
