Hi @Lanjewar, Hemant/Information Systems
Welcome to Microsoft Q&A! Thanks for posting the question.
As mentioned in the documentation - Virtual network support & private endpoint support private endpoints are supported only for the API and not for Azure OpenAI Studio.
If you are having issues with connecting the OpenAI API instance from your on-premises network, then can you please check if your IP network rule is setup to allow the internet-facing IP address. Please refer to the Configure access from on-premises networks documentation for details.
Please let me know if you have any questions.
Thanks
Saurabh
