Why can't I create a Delegated DNS resolver for my DNS-shared VPC?

Why can't I create a Delegated DNS resolver for my DNS-shared VPC?

When you configure DNS sharing for Virtual Private Endpoint (VPE) gateways, you might encounter issues. Often, you can recover by following a few steps.

The request fails when updating the DNS resolver type to Delegated on the DNS-shared VPC.

Possible causes include:

  • The DNS hub VPC must be disabled before you change the DNS resolver type.
  • The DNS hub VPC is not configured with a custom resolver.

To resolve this issue:

  1. Make sure that the DNS hub is enabled. For more information, see Enabling a VPC as a DNS hub.
  2. Enable a custom resolver in the DNS hub VPC. As indicated in the Getting started process, you must configure a DNS custom resolver on the hub VPC to be responsible for resolving DNS queries from hub and DNS-shared VPCs, as well as those from on-prem networks.
