MySQL Connection via PowerBI Gateway returns odd error

We set up a MySQL 8.0 server, uploaded some data, and connected a PBIX file to begin pulling data. The appropriate MySQL connectors have been installed in the MySQL Server and the PowerBI On Premise Gateway has also been installed on the MySQL Server. This server is a windows machine spun up on AWS.

 

When we upload the PBIX file to app.powerbi.com and setup the gateway to hit the AWS server, we keep receiving the following errors:

 

Unable to connect: We encountered an error while trying to connect to . Details: "We could not register this data source for any gateway instances within this cluster. Please find more details below about specific errors for each gateway instance."

To troubleshoot the connection, I tested the following:

From a separate machine, I can connect to the MySQL database using PowerBI Desktop.

From the AWS Machine, I can connect to the local MySQL database using PowerBI Desktop.

So I can connect to the MySQL server, and I can see the new gateway connection on app.powerbi.com.

 

However, when I attempt to create the data source connection, I keep running into the same 2 errors above.

I scoured the webs in search of an answer for my issue, and no luck.

I referenced this site: https://community.powerbi.com/t5/Service/On-Premesis-Gateway-cannot-connect-to-MySQl-source/td-p/717..., but I keep running into the same errors.

 

Any idea how this Renci.SshNet file needs can be located and addressed?

HI @humoon88 ,

According to your error message, I think this should more related to the compatibility of power bi and AWS datasource. If your report which create by mysql works well on power bi service side, I'd like to suggest your to open a support ticket to ask power bi team to check the backend status.(connection and authorizations)

submit a support ticketsubmit a support ticket
