Azure Data Factory Not Communicating via Private Endpoint

Question

After following the instructions to create a Private Endpoint and disable public access to the Azure Data Factory, the self-hosted Integration Runtime is unable to connect. What configuration am I missing?

Instructions followed: https://learn.microsoft.com/en-us/azure/data-factory/data-factory-private-link

Error: The access to data factory from public network is blocked.

The VM can resolve the private link. The private link is associated with Data Factory sub resource not portal. There are no NSGs blocking between the VM VNet and the Private Link VNet.

Hello @Anon4343 ,

Welcome to the MS Q&A platform.

The issue is, your SHIR VM is unable to connect to ADF associated with the private endpoint.

You can use one of the following options to configure your DNS settings for private endpoints:

1) Use the host file. You can use the host file on a virtual machine to override the DNS.

2) Use a private DNS zone. You can use private DNS zones to override the DNS resolution for a private endpoint. A private DNS zone can be linked to your virtual network to resolve specific domains.

3) Use your DNS forwarder (optional). You can use your DNS forwarder to override the DNS resolution for a private link resource. Create a DNS forwarding rule to use a private DNS zone on your DNS server hosted in a virtual network.

I hope this helps. Please let me know if you have any further questions.
