I want to insert data into and update a table in Azure DB for PostgreSQL using Data flow in ADF. But I cannot create connection between data flow and DB due to a network error.
Because of company policy, only private connections are available on the Azure network.
And the connection with SHIR is not allowed in dataflow so I tried to create the link service of Azure DB for PostgreSQL with managed private endpoint. But that connection failed.
The error message was
The value of the property '' is invalid: 'The remote name could not be resolved: '***.postgres.database.azure.com''.
The remote name could not be resolved: '***.postgres.database.azure.com'
What is the cause? I am concerned that the Managed Private Endpoint is "Provisioning". But I could not find the page to approve it.

I have no idea whether what I did was correct so any answer would be helped. What I want to do is to connect DB from dataflow using private network.
Thank you.
