Salesforce: Failed to update data source credentials
Since another Salesforce org connects successfully, this likely points to an org-level security setting rather than incorrect credentials.
Ask the Salesforce admin to check IP restrictions and “Lock sessions to the IP address from which they originated.” Also confirm that the user has API Enabled permission and that Power BI Service uses the correct supported custom domain, not a Lightning URL. Salesforce is a cloud source and normally does not need to be added as an on-premises gateway source.
Power BI Connector for Salesforce by Metrica Software provides another Salesforce-to-Power BI path:

It will not bypass Salesforce security restrictions, but it can simplify extraction with selected objects, fields, filters, preview, and SOQL support.
