Cannot connect my Power BI Desktop to a IBM DB2 database

I am not able to connect my Power BI Desktop to a IBM DB2 database. If I only add the server name and database I get an "Microsoft Db2 Client: No connection could be made because the target machine actively refused it 155.209.240.10:50000 SQLSTATE=08S01 SQLCODE=-1037". I was told to use port 8471, and adding serverort I get another error. I have tried using both IBM and Microsoft Driver. On next page I have added "Database" user that works with ODBC/WinSQL as we do not have the same Using IBM Driver I get "DB2: We were unable to find a database provider with invariant name 'IBM.Data.DB2'" and I tried to install the recommended "Data Server Driver Package (DS Driver)". Is there any guide, or anyone that have had issues that can share what they did to get it to work? The server is hosted at a hosting partner. I can connect using ODBC but then we need to install Client Access to all users, and it is working really slow.
