Hi  Anonymous ,

You can try the following:

Go to “File –> Options and Settings –> Options –> Data Load and delete cache files.
Go to File -> Options and  Settings -> Data Source settings. A window with all connections you have will appear. Select the SQL connection and at the bottom of the window click edit..Update the credentials.

Ensure that SSMS is installed on the same machine with Power BI Desktop.

Besides, please follow the instructions in the article below to troubleshoot this connection error.
