Help with recent problem with automatic updates

Hi Danort123 - This type of error often indicates that there’s been a change in security protocols—either on SharePoint’s side or due to system or Power BI service updates.

Ensure that your environment (Power BI Desktop or Gateway) supports TLS 1.2 or higher, as Microsoft has deprecated earlier versions (TLS 1.0 and 1.1).
To check this, make sure your system is configured to use TLS 1.2 by default. On Windows:
Open Internet Options → Advanced tab.
Under “Security,” check that "Use TLS 1.2" is enabled.

If the update involves connecting to a SharePoint site, verify that the credentials used for the connection are still valid and have the necessary permissions.
Re-authenticate the SharePoint data source in Power BI Service by going to Settings → Datasets → Data source credentials, and re-entering the credentials for the SharePoint connection.

If you're using an On-Premises Data Gateway, you might need to configure it to use TLS 1.2 by default. You can do this by modifying the system registry on the machine where the gateway is installed. Here’s how:
Open the Registry Editor.
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols.
Ensure that TLS 1.2 is enabled in both the "Client" and "Server" subkeys.
Restart the gateway machine after making changes.

still issue exist, consider using Power Automate to pull SharePoint data into a more accessible location (e.g., an Azure SQL database or a CSV file in a secure storage account), then connect Power BI to this intermediary source instead of SharePoint directly.

Hope this helps.
