The Azure Machine Learning integration is not currently supported in Synapse Workspaces with Data Exfiltration Protection

Question

Hello Microsoft Q&A,

we are using a Azure Synapse Workspace and a Azure Machine Learning Workspace for quite some time now. The Synapse Workspace has a activated Data Exfiltration Protection. The connection between these two resources is not working any longer. When running a pipeline reading data from the ADLS Gen2 storage of the Synapse Workspace in the MLW I get the following error:

Error Code: ScriptExecution.StreamAccess.NotFound
Native Error: error in streaming from input data sources
	StreamError(ConnectionFailure { source: Some(hyper::Error(Connect, ConnectError("dns error", Custom { kind: Uncategorized, error: "failed to lookup address information: Name or service not known" }))) })
=> connection failure when access stream
	ConnectionFailure { source: Some(hyper::Error(Connect, ConnectError("dns error", Custom { kind: Uncategorized, error: "failed to lookup address information: Name or service not known" }))) }
=> error trying to connect: dns error: failed to lookup address information: Name or service not known
	hyper::Error(Connect, ConnectError("dns error", Custom { kind: Uncategorized, error: "failed to lookup address information: Name or service not known" }))
=> dns error: failed to lookup address information: Name or service not known
	ConnectError("dns error", Custom { kind: Uncategorized, error: "failed to lookup address information: Name or service not known" })
=> failed to lookup address information: Name or service not known
	Custom { kind: Uncategorized, error: "failed to lookup address information: Name or service not known" }
Error Message: Connection failed when trying to access the stream. Make sure uri is correct. error trying to connect: dns error: failed to lookup address information: Name or service not know

I struggeled to find a reason. But now I read that:

Is there a workaround for this problem?
