Dataverse connexion using DirectQuery not fonctionnal

Hello everyone,

We are trying to create a report using a connexion to Dataverse and the DirecQuery feature and unfortunatly after many attemps, it is still giving us a error:

Microsoft SQL: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server).

We checked if the TDS feature for power apps is activated and it is;

I have global admin right;

We triple check the url for the environment and it is good;

We tried the legacy connexion with CDS and we can link the table no problem;

Another colleague tried to do the connexion, same result same message. 

Could it be related to the data center ? we are based in Canada. Any help on this issue would be greatly appreciate.

Thank in advance for your help and support.
