MySQL Authentification Error with On Premises Data Gateway

Anonymous — Thu, 02 Jun 2022 15:40:54 GMT

Hi everybody,

Very frustrating issue and I can't find the same exact issue anywhere else.

I have a MySQL connection which works fine on Desktop, but on PBI Online, when using On premises data gateway it gives me an Authentification Error (code : -2147467259).

The gateway is running well, as we are using it already with Power Automate and Power Apps. But when I try to configure the data source to the gateway, it doesn't recognize my authentification (method : Basic, username + password).

Am I missing something ?

Thank you for the help!

Antonio

Long standing issue. MySQL and Microsoft blame each other. We have a dedicated gateway with an ancient version (66.8) solely for MySQL refreshes.

Hi,

Thanks for that answer. So it does work with the ancient version ? Do you know where I can find it ?

Thanks again,

Antonio

Hi Anonymous ,

Or you can also try going to File|Options and Settings|Data Source Settings and Edit Data Source. Change the credentials to database credentials instead of Windows credentials, then republish.

Refer to the following related blog entry:

If the problem is still not resolved, please provide detailed error information and let me know immediately. Looking forward to your reply.

Best Regards,
Henry

There is no version 66.8 in this page...

Hello,

Thanks for your answer.
I already had permissions set to database credentials.
The error occurs when trying to connect the data source to the gateway. Even when I set "Skip Test Connection", when I force a refresh online this is the error that I have :

Underlying error code: -2147467259
Underlying error message: The credentials provided for the MySql source are not valid.

It seems to be a problem of credentials, but I'm sure I have put the right username/password combination.

Thanks a lot for your help!

All the best,

Antonio

Hello everyone,

I opened a support ticket and the Microsoft Support Team found a solution to this problem. Here's what we had to do :

On Power BI Desktop :
- Clear cache and then cleared permission from data source settings.
- refresh and put all the credentials again
- Publish it to the service.
On the online service :
- Add new datasource to the gateway (with old UI link, so that credentials are not required: https://app.powerbi.com/groups/me/gateways?newManageGatewaysUI=false) and gave same privacy level as power bi desktop.

Online refresh worked fine after that.
