All,

i cannot create index following instructions in "Exercise - Create a generative AI app that uses your own data".

Hello Kelman,

Thank you for posting on Microsoft Learn !

I think you have network connectivity issues between your environment (like your browser or cloud shell) and the Azure service.

If you're running anything locally (through a notebook or Azure CLI):

• verify your machine is connected to the internet
• check firewall or proxy settings, especially if you're on a corporate network
• try accessing the Azure portal or other HTTPS endpoints from a browser

Also, make sure you're targeting the correct Azure region and endpoint for your Azure AI Search or Azure AI Studio resource. For example:

If your resource is in eastus, make sure you're not trying to hit a westeurope or default region endpoint.

Hello Kelman !

Thanks for sharing the follow-up, you’re absolutely right to point out how misleading that error is.

Free tier supports only a single replica and a small number of indexes (typically 3).

It often doesn’t support features required for vector indexing, semantic ranking, or complex data ingestion.

You can leave product feedback requesting clearer errors for unsupported tier features for example “Operation not permitted on Free tier” instead of misleading connection errors.
