Hi BM,
Thank you for posting query in Microsoft Q&A Platform
Could you please try below steps and see if that helps?
- Create a virtual network in Azure that will be used to host the private endpoint.
- Create a private endpoint in the virtual network for MongoDB Atlas. This will allow Azure Synapse to access MongoDB Atlas through the private endpoint.
- Configure the private endpoint to use a private IP address that is within the same IP address range as the virtual network used by Azure Synapse.
- Configure the MongoDB Atlas cluster to allow traffic from the private IP address range used by the virtual network.
- Configure Azure Synapse to use the private endpoint to access MongoDB Atlas.
If above not helps, then you might need to consider using SHIR.
Hope this helps. Please let me know how it goes.
