Report using Excel File in SharePoint documents fails for path error

I developed a report that connects to an Excel file I stored in a SharePoint document library. 

Some parameters that will help: 

* Our SharePoint is on-prem. 

* I am using an Enterprise Gateway on a server. 

* There are other reports running sucessfully against Libraries on the same sharepoint instance.

* I have the excel data and other sharepoint data, populating different tables, in the same report. 

 

The report works fine from my desktop, I can refresh the data all day.  I uploaded it to power bi online and tried to update the gateway with the connection.  I get an error the file cannot be found.  I can take the URL and paste it in windows explorer and the file opens.  (Yes, I did alter the sharepoint instance name to hide my company info)

 

Any suggestions?

Re: Report using Excel File in SharePoint documents fails for path error

If you were to log onto the server that holds your gateway, are you able to access that SharePoint address exactly as it is written?

 

To put it in another way.  If you had a file on your local computer you would access it like "C:\Folder\File.ext"  however another computer would access it like "\\Computer\Folder\File.ext".

 

So firstly, the gateway, using the credentials provided, would need to access the SharePoint folder using the exact address you placed into your data source.  In my above example the "C:\Folder\File.ext" wouldn't work on a gateway.  SharePoint is obviously not a local file system, so the access credentials also come into the mix.  There is also the case of where you gateway sits on the network and whether that SharePoint address is accessable from that part of your network.

Re: Report using Excel File in SharePoint documents fails for path error

Well crap, I should have thought of that.  I think in my head, I assumed if other lists were available then the document library should be.   And the answer is no, so I need to check with my firewall team.

Re: Report using Excel File in SharePoint documents fails for path error

Any suggestions on sources for blocking a UNC path from the server?  I checked our firewall and there was no blocked traffic.  I am a site collection admin on sharepoint so its not a permissions issue.  What else can I check?
