Internal Error connecting PowerBI to MySQL database



I am currently trying to connect a dashboard I designed with a MySQL database holding the data currently. However, I keep receiving this error: Details: "An error happened while reading data from the provider: 'Internal connection fatal error. Error state: 18'".


Is this an issue with PowerBI's side or the host's side and is there a way to fix this? 


Thank you.

Hi @DrinkableRiver ,

In your scenario, are you able to connect to the MySQL database in MySQL workbench? Please ensure that MySQL workbench is installed in the same machine as Power BI Desktop.

If the connection is successful in MySQL workbench, use same connection string and make sure that you use Database credential in Power BI Desktop to connect to the MySQL database, and you can review this blog about connecting to MySQL in Power BI Desktop.

If this post was helpful may I ask you to mark it as solution and give it some kudos?

Have a nice day!


Thank you for responding.


Unfortunately, even after trying those methods I am still receiving the same error.


Do you know of any other potential solutions perhaps? 

Have you found any solution for this issue? I am able to connect to the Azure MySQL using Workbench but I am getting the same error as yours while connecting the PowerBI data source to Azure MySQL
