This error occurs when Power BI is unable to decrypt the credentials used to access a data source. In this article, we will explore the causes of this error and provide troubleshooting solutions to resolve it.

Understanding data source credentials and credential decryption in Power BI

Before we delve into troubleshooting the ‘Data Source Credentials Could Not be Decrypted’ error, it is essential to understand the concept of data source credentials and credential decryption in Power BI.

Data source credentials are the credentials required to access a data source, such as a database or an API. These credentials are typically stored securely by Power BI to ensure the data’s confidentiality.

Credential decryption is the process of retrieving and decrypting the stored credentials to establish a connection with the data source. Power BI uses various encryption algorithms to protect the credentials, ensuring that they are not accessible to unauthorized users.

However, sometimes, issues may arise during the decryption process, leading to the ‘Data Source Credentials Could Not be Decrypted’ error.

Common causes of the ‘Data Source Credentials Could Not be Decrypted’ error

Several factors can contribute to the occurrence of the ‘Data Source Credentials Could Not be Decrypted’ error in Power BI.

One common cause is an incorrect or outdated password for the data source. If the password has been changed since the data source connection was established, Power BI will be unable to decrypt the credentials, resulting in the error.

Another cause can be a disruption in the connection between Power BI and the data source. This disruption can occur due to network issues, server downtime, or changes in the data source’s configuration.

Additionally, if the data source is using a different encryption algorithm than Power BI, the decryption process may fail, leading to the error.

Basic troubleshooting steps for resolving the error

When encountering the error in Power BI, there are several basic troubleshooting steps you can take to resolve the issue.

First, ensure that you have entered the correct credentials for the data source. Double-check the username and password, ensuring that there are no typos or errors.

If the credentials are correct, try restarting Power BI. Sometimes, a simple restart can resolve temporary issues that may be causing the error.

Additionally, check if there are any pending updates for Power BI Desktop. Keeping your software up to date can often resolve compatibility issues and improve overall performance.

If restarting Power BI and updating the software do not resolve the error, try clearing the stored credentials for the data source.

To do this, go to the “Options” menu in Power BI Desktop, select “Data source settings” and click on the “Clear Permissions” button next to the data source causing the issue.

This will remove the stored credentials and prompt you to enter them again, potentially resolving the decryption problem.

Advanced troubleshooting solutions for resolving the error

If the basic troubleshooting steps fail to resolve the error, there are advanced solutions you can try. One such solution is to check the Windows Credential Manager.

Windows Credential Manager stores credentials for various applications, including Power BI. Check if the stored credentials for the data source are correct and up to date. If not, update them accordingly.

Power BI Error Troubleshooting

Another advanced troubleshooting step is to recreate the data source connections in Power BI. Sometimes, the issue may lie with the connection itself rather than the credentials.

To recreate the connections, go to the “Edit Queries” option in Power BI Desktop, select the affected data source, and choose the “Edit Credentials” option.

Re-enter the credentials and test the connection to see if the error persists.

Delete the credentials.bin file

Navigate to ‘C:\Users\USER_ID\AppData\Local\Microsoft\Power BI Desktop\\Credentials‘ and delete the file called credentials.bin

In case the AppData folder is hidden from the user, it can instead be accessed from within the Power BI Desktop application.

Go to File -> Options and Settings -> Options and select ‘Auto Recovery‘ Global setting.

Click on the ‘Open auto recovery folder‘ button, this will open the hidden folder for the user.

Then navigate one level up and into the \\Credentials subfolder and delete credentials.bin file.

Furthermore you can activate the ‘Show hidden files, folders and drives‘ option from the Windows Control Panel.

This option should enable you to see the hidden AppData folder.

Once the credentials.bin file has been deleted, launch Power BI and open any .pbix file to test whether the issue has been resolved or not.

Leveraging the Power BI community forums for resolving the error

If you have exhausted all the troubleshooting solutions mentioned above and are still unable to resolve the error, it can be beneficial to seek help from the Power BI community forums.

The Power BI community forums are a valuable resource where users can ask questions and share their experiences. Furthermore you can seek assistance from fellow Power BI enthusiasts and experts.

When posting on the community forums, provide detailed information about the error. Include all the steps you have already taken to troubleshoot.

Be sure to mention the data source type, the encryption algorithm used, and any other relevant details.

The community members can provide insights, suggestions, and solutions based on their expertise, helping you overcome the error.
