Gateway connection to SQL Server failing

Hello,

I tried to connect my Gateway (named "Datam Server") to a SQL server with Windows authentication (I've done this before with basic authentication but I don't have database credentials this time) and it won't work. THe Gateway shows me this error:

When I built the PBI report I had no trouble using Windows authentication but the wateway just don't work.

I have noticed that the cluster URI stands for US but I'm on Europe, Could this be part of the issue?

ANy help would be really appreciated  

Regards!
