Power Bi Report Server could not connect to the data source Sharepoint

[Anonymous]

Hello!!

It's my 1st time using Power BI Report Server, and I'm having many problems on the path.

Now, ones that I upload from PBI RS (I had to download the version january 2021 because the RS folder where I have to upload the document, doesn't allowed upper versions) to the RS folder the client has created for my proyect (january 2021) i'm trying to prgramm the scheduled update, but an error message pop up:

Translation:

The report server could not connect to the data source with the information you entered. Make sure that you have entered the connection string and credentials correctly.

The data source of the proyect are sharepoint lists (local). The connection string it's the same I used on POwer BI when developed the dashboards. I used the right credentials, the right username and password.

What might be the problem? 

Thank you in advance for helping me

You may need to enter the username in the form of <domain>\<username> if you just enter the username it *may* default to attempting to authenticate as a local user on the server.
