Issue refreshing a SAP (connector 2.0)

Hi all,

I've experienced issues while trying to setup automatic refresh of a BW4 datasource in power BI service.

-> Dataset is using connector 2.0

-> I'm not using SSO and the account is working fine

-> The gateway is up and running & there are no firewall issues (with our onprem BW server) on the machine running it

-> .Net connector 3.0 is installed on the machine (x64 version)

-> I'm using import data 

-> The report works fine on power bi desktop and refreshes without any problem ( & it has very little data in it).

In power bi service, when i try to create the connection, i get the following message:

However, connector 2.0 isn't supposed to use the RFC libraries.

-> I even installed SAP GUI on the machine (that comes with some libraries)

Have you guys any idea of what did i do wrong?

Thx

Best regards
