Helper IFailed to Test Connection to your Data Source - Retry Credentials - Only On Certain Reports
Hi,
A new issue it seems - I am getting on the below messages on my credentials (for databases) within Power BI Service.
This is on a newly uploaded file, which refreshes fine with desktop, and other reports within service use the exact same connection and refresh fine within Power BI service - its connection to our two main databases so we've got 30+ datasets that all uses them in some capacity.
However, even existing ones show this error as well when I check, but do refresh if I trigger it within service, but any new reports, like this one, fail on refresh and I can't set up new schedules.
Only started in the last day or so. Is this a bug within Power BI Service at present?
As I say, all connections refresh fine in Desktop, and existing reports in Service (not uploaded in the last day or so) continue to refresh upon schedule and manually.
When I do try to edit the credentials and re-enter the user name and password I get the following error, which leads me to believe this is an error on Microsofts side.
Hi, MainlineData
Thank you very much for your reply. This is documented in the official documentation:
Power Query MySQL database connector - Power Query | Microsoft Learn
As mentioned earlier, you can connect to MySQL using a standard gateway (Enterprise Gateway) or connect to your MySQL using a cloud link.
In addition, you can also refer to the following article to connect to your MySQL using dataflow:

Hi, MainlineData
In this case, there is an issue with your data source credentials, and you can try creating a new connection in Power BI Service. This connection will connect to your data source, and then configure the current new connection for the newly reported semantic model, instead of updating the credentials.
Also, whether other old reports that you use the current data source will be able to refresh? It's just that your new report has the current refresh error?

MainlineDataHi,
When I've dug into this further, my core issue is linked to other behaviour that other users have found - that Power BI is treating a mySQL connection as a cloud source when it isn't (and isn't then using on-premise gateway).
See this ticket for best description - https://community.fabric.microsoft.com/t5/Service/PowerBI-Recognizes-mySQL-as-Cloud-based/m-p/3843180
I've just knocked the tower over by trying to investigate why this one report wouldn't work, and now knocked them all over.

I had also checked my credentials multiple times, and tried recreating connections, and even deleting / reuploading.

Hi,
On power bi service please check whether the personal gateway connection is coming online or not.And you can check with your tenant admin he will help in setting up an on-premises data gateway connection.
