I'm checking your support to understand the connection failed over when I need to build new connections.
I can input the credential of the old connection, but not for new one. Please advice,

RequestId: 02fdd56c-425d-4b4b-a67e-dc2809b796d8

Status code: 400

Thanks All for your input,
Actually I still didn't find why the existing connection working well with user/pwd authentication in existing report, but not able to create new connection with different directory in (folder/ file/ sharepoint...).
@Anonymous can you check more whether any restriction in Admin role to revoke create new connection?
If no stoper, we can have quick sharing on Monday Oct 21 2024, at 11AM China-time?
Thanks again,

Hi, @Thas_Michael
The status code is 400, which means that the Power BI service cannot connect to your data, your data source is not unreachable.
Here are the steps you need to take:
You need to make sure that the credentials provided are the same as in Power BI desktop:

Additionally, you need to ensure that your data sources do not intercept requests to the Power BI service.

Thanks,

what do mean by "build new connections"?

Pls provide more information what are you aiming to achieve.

Your error indicates that the data source credentials are not correct.
