Missing several database connectors

[Andreas6]

My Power BI Desktop (Version: 2.143.878.0 64-bit (May 2025) is not displaying several certified database connectors under "get data". The list ends at "AtScale-Models" although there should be more connectors visible (as I see on another computer device) like ClickHouse, Denodo, Exasol, MariaDB. Here is a screenshot of some of the missing connectors that I see on my other device.

I need the MariaDB connector but there seems to be a general problem with the loading of connectors. The machine is a Windows Server 2016 Standard x64.

Visual C++ 2015-2022 Redistributables are installed for x64 (version 14.42.34433) & x86 (version 14.42.34438)

.NET Framework 4.8 is installed.

Any hints are appreciated!

Hi @Andreas6 ,

Just checking in have you received the support ticket we raised? If so, do you have any updates from the support team?

[Andreas6]

Thanks, I didn't receive a support ticket but the problem was solved now. Looks like one of the Power BI sites was blocked on the machine. I can see the MariaDB connector now.

Hi @Andreas6 ,

Thank you for reaching out to the Fabric Community. In addition to @freginier , response, I have checked my own system and can confirm that the MariaDB connector is available in Power BI Desktop.

FYI:

This indicates that the issue is specific to your environment. It seems that your Power BI installation might be incomplete or corrupted, preventing some connectors from loading properly.

Although Power BI Desktop is supported on Windows Server 2016, this operating system is relatively outdated. Newer Power BI versions may rely on specific Windows updates or components that are not present or fully supported on older server OS versions.

You've confirmed that Visual C++ 2015-2022 Redistributables are installed for x64 (version 14.42.34433) & x86 (version 14.42.34438), .NET Framework 4.8 is installed. These are good steps, but we will verify and update these dependencies as needed.

Please reinstall Power BI Desktop using the official standalone installer from https://powerbi.microsoft.com/desktop, not the Microsoft Store version.

Thanks for the hints. I tried to reinstall the standalone version of Power BI several times, but without success. There is also no warning or error message in Power BI during installation. Is there any log where errors are traced? I didn't find anything related to MariaDB in the standard logs.

I have the same problem on Windows Server 2019 Standard, if this OS is supported as well.

Hi @Andreas6 ,

Thanks for the update. Based on your description and the fact that the MariaDB connector is available on your other (presumably internet enabled) machine, it’s very likely that restricted outbound connections are preventing Power BI Desktop from retrieving and loading certain certified connectors.

While the standalone MSI installer includes the core application and many data connectors, some certified connectors  like MariaDB  rely on runtime access to Microsoft cloud based connector registry to be fully visible and functional.

Please try the following

1. Temporarily allow outbound internet access on the machine.

2. Launch Power BI Desktop and check under Get Data to see if the MariaDB connector becomes available.

I hope this helps..

Hello team, 
I am facing the same issue. 
I would like to temporarily allow outbound internet access but my CISO is asking to limit to a white list of domain. Any idea regarding the white list ? 
Is *.microsoft.com enought ?

Many thanks for your help

Hi @Dimitri_MM ,

Thank you for bringing this up, it's a common issue in secure environments, and it's important to consider domain specific whitelisting.  Power BI Desktop needs runtime access to Microsoft’s cloud based connector registry to display certain certified connectors like MariaDB, Denodo, and Exasol. 

You can find the official allowlist guidance here:

• Reinstall Method: Try installing from the Microsoft Store (if you used MSI) or vice-versa.
• User Profile: Test Power BI Desktop under a different Windows Server user account.
• Network/Security: Check server firewall, proxy, or antivirus blocking outgoing connections.
• Clean Reinstall: Perform a very thorough uninstall (including leftover folders) then reinstall.
• Clear Cache: Clear Power BI Desktop's internal cache via File > Options > Data Load.
• WebView2 Runtime: Manually install or repair the Microsoft Edge WebView2 Runtime.
• MariaDB ODBC Driver: Ensure the 64-bit MariaDB ODBC driver is installed on the server.

Thanks for the checklist!

• Reinstall Method: Try installing from the Microsoft Store (if you used MSI) or vice-versa.
  • I have no access to the Store on this machine, but the MariaDB connector should be available on the standalone installer as I see on my other machine.
• User Profile: Test Power BI Desktop under a different Windows Server user account.
  • Ongoing.
• Network/Security: Check server firewall, proxy, or antivirus blocking outgoing connections.
  • Outgoing connections are restricted on the machine, may this be the cause? Shouldn't the standalone installer work offline?
• Clean Reinstall: Perform a very thorough uninstall (including leftover folders) then reinstall.
  • Tried, no success.
• Clear Cache: Clear Power BI Desktop's internal cache via File > Options > Data Load.
  • Tried, no success.
• WebView2 Runtime: Manually install or repair the Microsoft Edge WebView2 Runtime.
  • Installed, no success.
• MariaDB ODBC Driver: Ensure the 64-bit MariaDB ODBC driver is installed on the server.
  • Installed, no success.
