How to connect TSI on Public endpoint to Iothub on Private endpoint with data flow

I have a TSI on the public endpoint and a Iothub on private endpoint
But the data is not flowing from Iothub to TSI.
Is there a way to have the data flow with the above setup

Hi @VikasRajareddy-9365 ,

If you disable public network access, the built-in Event Hub compatible endpoint is disabled as well (since Sep 30, 2020, see iot-hub-public-network-access-bug-fix).
To allow TSI or other services, which are not part of your VNET, to access the Event Hub compatible endpoint, you need to allow public network access again and use IP filter to control public access to the built-in endpoint.

If both TSI and Iothub are in the same Vnet, will the data flow happen.
If yes, then how can we achieve it and how to check the data in the TSI present in Vnet

Note: Basically we need everything to be on private endpoint

Have you checked how-to-private-links to enable Private Link for TSI?

If TSI and IoT Hub are in the same VNET, TSI should be able to access the built-in end point via the private endpoint.

We have created the private endpoint for TSI and tried to access the TSI from the VM present on the same Vnet, but we are not able to see the TSI environment and the data

Is there a separate address(url) to access the TSI explorer present on the private endpoint

You should be able to see the private endpoint listet in the private endpoint connections of you TSI instance or in the Private Link Center in the Azure Portal.

we are able to see the private endpont for the TSI, but the TSI explorer is not launching
Is there any specific permissions needed to view the TSI explorer in private endpoint
