Hi
I think this is the appropiate place to put this, so here goes.
I have a site, where I have installed the on-premises PowerBI Gateway, and added a data source, the Analysis Services instance, that is installed on the same server as the gateway.
Testing connection gives green a-OK checkmarks.
When I try to get data from the AS database, I press get data --> SQL Server Analysis Services --> Connect --> choose the data source --> and gets this error message: Something went wrong, and for the record "følgende systemfejl opstod" translates to: The following system error occured.
I have of course clicked the link, but it gives this guide: https://powerbi.microsoft.com/en-us/documentation/powerbi-gateway-onprem/
And it is the on-premise gateway I have installed.
The SQL server is 2016, now with SP1, (yesterday it was RTM version, but no change after update)
SQL Server 2016 (SP1) (KB3182545) - 13.0.4001.0 (X64)
To make sure it is not a rights-issue, the powerBI account used for the gateway is also administrator on the Analysis Services instance, and so far is the only account used.
I have made installations like these a couple of times before, but the lack of error description in the interface is something I haven't seen before.
The log mentions 'AdomdErrorResponseException' but the adomd.net / Analysis Mangement object are both installed on the server, as 2016 versions, from the installation of the SQL server I assume.
I tried to paste the log in a code block, but my post became to long. I have pasted it here: http://pastebin.com/N1iJyG5M I hope it is ok.
Any help is greatly appreciated as I can't interpret the log myself. I have found other similar threads with similar issues like this one: https://community.powerbi.com/t5/Service/Enterprise-Gateway-can-t-connect-to-on-premise-AS/m-p/13736#M4807
But they are all about needing updates to older SQL server versions. But as this is SP1 on 2016, I don't really have that option.
