Connection to SQL via Data Gateway fails: Error occurred while decoding OAEP padding.

Get this error when trying to connect to our SQL Server on-premis using enterprise data gateway, and when using File option.

Unable to connect: We encountered an error while trying to connect to SQLServer. Details: "There was an error in the data gateway."Hide details

Status code:	400
Error Code:	DM_GWPipeline_UnknownError
Time:	Thu Aug 24 2017 13:28:47 GMT+0200 (Central Europe Daylight Time)
Version:	13.0.2136.181

Underlying error message:	Error occurred while decoding OAEP padding.
DM_ErrorDetailNameCode_UnderlyingHResult:	-2146233296

I connect with windows credentials, credentials are working from the Data Gateway server, 

I installed the gateway to days ago, should be the latest version.

Any ide why this message is happening? I found something on the community, a suggestion to replace the msolap.dll file, however the file is not longer accessible from the forum.

@HaraldK,

Do you use "File" data source type in Gateway to add the SQL Server data source? If so, when adding SQL Server data source within gateway, we need to choose "SQL Server" type, please follow the guide in this article to perform the process.

Lydia
