Gateway errors in Power BI are often caused by a mismatch between the data source information and the underlying dataset. To solve this problem, you need to ensure that the data source defined on the local data gateway is accurate and consistent with the data source specified in Power BI desktop.
If Power BI cannot connect to a data source and encounters an error when trying to connect, you may be facing one of the following issues.
Let’s talk about it in detail.
When Power BI fails to register a data source for a gateway instance, it displays the following error message in the data source domain.
Unable to connect: An error was encountered while trying to connect to filename.xlsx. Details: We cannot register this data source for any gateway instance in this cluster.
When encountering this error, you must be sure to provide an accurate UNC path. The UNC path only includes the server name. If the server name is fs1, the UNC path should be \fs1. Avoid including the domain name in the string and contact your IT administrator for the exact server name. Entering the correct format will solve the problem.
Power BI refusing to connect to a data source is a common problem, especially when trying to connect to HTML source code. In this case, the user may encounter an error message stating that the connection cannot be established.
However, some people have encountered this problem when connecting to HTML sources and got this error.
An error was encountered while trying to connect.
Details: "The downloaded data is Hypertext Markup Language, which is not the expected type. The URL may be wrong, or you may not have provided the correct credentials to the server."
When connecting to an Excel workbook, the following error occurs.
Details: "Excel workbook: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local computer.
In the case of the HTML file, we are still using the Excel file as the source, so why not create an offline copy of the same file and use it as the data source? However, if you still want to import it from an online platform like OneDrive, you have to make the following changes.
You will then see a dialog box where you can enter all your details, you can follow the on-screen instructions to navigate, and you're good to go
But if you can't import an Excel file, there's no need to indulge in all these shenanigans; you can just do what the error message says. That is, download the client software from the link mentioned above. However, we recommend that you contact your IT administrator and ask them for the appropriate link to download the tool, as the company may have some policies prohibiting downloading certain content from external sources.
