SAP BW and Power BI integration

Hi All,

We are trying to create a connection with SAP BW from Power BI services through gateway through SSO authentication. We have already reffer the below document and implemented all but still getting the below error.

powerbi-docs/powerbi-docs/connect-data/service-gateway-sso-kerberos-sap-bw-commoncryptolib.md at live · MicrosoftDocs/powerbi-docs · GitHub

Any idea what could be the reason?
