Error Message:
I have an Azure AI Search service, and its networking status is set to "Public Network Access from all networks". There are no additional networking configurations. It has an index which has been run on a blob storage account. I also have an Open AI GPT 3.5 deployment which I just created a hub for in the new interface.
However, when trying to connect my index from the Azure AI Studio interface, I keep getting the following error
"403: A Virtual Network is configured for this resource. Please use the correct endpoint for making requests. Check https://aka.ms/cogsvc-vnet for more details."
Why is this happening even though there are no VNet configurations for the Azure Search
Solution:
Basically the problem was that even though my Search Service was configured for public access, I had a private endpoint connection to the Storage Service. The private endpoint was disconnected, but I had to delete it to make it clear to the AI Service that the access should be public.
If you have any other questions, please let me know. Thank you again for your time and patience throughout this issue.
