I am working on using Azure Openai on Azure Search Indexes .
It’s in private environment Vnet ,and tried with sdk and ai studio portal .

Isolated ,each service gives result in sdk-portal but on adding search service index as a data source in openai ,it gives error
‘Outgoing traffic to hostname ‘aiservice.windows.net’ is prohibited . hostname FQDN not in the allowed list of this resource’ .

Openai has the necessary rbac role to read index and shared private access between both.

It read like connection issue,but I am unable to resolve the problem .

I tried adding both to private DNS zone config under vnet but same error persists .
