ADF unable to call internal API via web activity with self-host Integration Runtime
Hi, I am working on a project with Azure Data Factory.
We have setup an internal application and provided a API for updating record, and we would like to trigger a POST call by web activity in ADF (with Self host IR), but failed with the follow message:
Error code: 2108
Failure Type: User configuration issue
Details:
Error calling the endpoint 'https://<internal domain>.com'. Response status code: 'NA - Unknown'. More details: Exception message: 'NA - Unknown [ClientSideException] An error occurred while sending the request.'. Request didn't reach the server from the client. This could happen because of an underlying issue such as network connectivity, a DNS failure, a server certificate validation or a timeout.
(FYI the ADF is adopted with private endpoint, and tested the self-hosted IR can call the API using postman)
I saw the similar questions here but didn't mention if the API is internal.
May I know if there is any similar use case and how to solve this problem?
