As an experienced tutor registered on UrbanPro.com specializing in Microsoft Power BI online coaching, I understand that encountering data connection issues is a common challenge. Here's a comprehensive guide to help you troubleshoot and resolve these issues efficiently.

1. Verify Data Source Credentials

• Ensure that the credentials used to connect to the data source are correct.
• Check if the username, password, and other authentication details are accurate.
• Confirm that the account used has the necessary permissions to access the data.

2. Check Network Connectivity

• Validate that your internet connection is stable and reliable.
• If using an on-premises data source, ensure that the Power BI service can access the data source server.

3. Refresh Permissions

• Confirm that the dataset and data source permissions are configured correctly.
• Check if your account has the necessary permissions to refresh the data.

4. Review Connection Settings

• Examine the connection settings in Power BI Desktop.
• Ensure that the connection information, such as server name and database name, is accurate.

5. Use the Power BI Service for Testing

• Test the data connection directly in the Power BI service.
• This helps identify whether the issue is specific to Power BI Desktop or if it persists in the online environment.

6. Update Power BI Desktop

• Ensure that you are using the latest version of Power BI Desktop.
• Updates often include bug fixes and improvements that can address connectivity issues.

7. Firewall and Antivirus Settings

• Check if your firewall or antivirus software is blocking the connection.
• Configure firewall settings to allow Power BI access to the internet and necessary data sources.

8. Review Query Folding

• If using Power Query, check if query folding is occurring.
• Some data sources may not support query folding, leading to performance issues.

9. Data Source-Specific Troubleshooting
