Unable to Connect Azure AI Search with AI Foundry in Korea Central Region

Question

We are encountering an issue when attempting to integrate Azure AI Search with AI Foundry, where both services are deployed in the Korea Central region. The connection consistently fails in this configuration.

As a comparison, we deployed the same setup in the East US region and the connection works as expected. This confirms that the configuration and credentials are correct and valid.

While debugging the failed connection in Korea Central, we inspected the network request and found it returns a 404 - Resource Not Found error. However, the Azure AI Search resource is verified to exist and is accessible from other services.

This suggests a possible regional service limitation, internal routing issue, or misconfiguration in Korea Central.

We would appreciate your assistance in:

Investigating whether this integration is fully supported in Korea Central,

Identifying any known limitations or issues with AI Foundry or Azure AI Search in this region,

Providing guidance or a workaround for successful integration.

Please let us know if you require additional information such as subscription ID, resource names, or error trace logs.

Hi Marchel Maulana Fahrezi,

The 404 error you're encountering when integrating Azure AI Search with Azure AI Foundry in the Korea Central region likely stems from regional service limitations. While your configuration works in East US, certain features required for this integration may not be fully supported in Korea Central.

Regional Availability of Azure AI Search Features:

Azure AI Search's advanced features, such as AI enrichment and semantic ranking, depend on co-located Azure AI services within the same physical region. These features are not uniformly available across all regions. Specifically, AI enrichment requires that Azure AI Search and Azure AI services reside in the same region, and this integration is not supported in Korea Central.

Azure AI Foundry Feature Support__:__

Azure AI Foundry allows adding features from different regions to your project. However, you may need to use a different region for a particular feature based on its availability. It's essential to verify the regional support for each feature you intend to use.

Please refer to the documentation: https://learn.microsoft.com/en-us/azure/ai-foundry/reference/region-support?utm_source=chatgpt.com

Recommendations Options:

Please follow the steps mentioned in this document: Configure Azure AI Search

·   Consider Alternative Regions: If critical features are unavailable in Korea Central, deploying your services in a region like East US, where full support is confirmed, may be necessary.

·   Use Identity-Based Connections: Azure AI Search supports identity-based connections, which can bypass certain regional limitations. This approach is currently in public preview and may offer a viable workaround.

Hope this helps, do let me know if you have any further queries.

Thank you!
