Getting datasource credentials error in Power-BI service for AWS PostgreSQL

Hi , VishrantiC 

Based on my research and investigate on the issue you met in the Power BI service currently, this error message indicates that there is a connectivity issue between Power BI Service and your AWS PostgreSQL data source. Here are some troubleshooting steps you can try to resolve the issue:

1 Check if the AWS PostgreSQL data source is accessible from the internet. You can try to connect to the data source using a tool like pgAdmin or psql from a machine outside your network to see if you can establish a connection.

2 Check if the firewall rules on your AWS PostgreSQL data source allow traffic from the Power BI Service IP addresses. If the Power BI Service IP addresses is changed every time and we can guarantee, We suggest to connect it using on-premise data gateway because the IP sent from on-premise data gateway is stable:

Add or remove a gateway data source - Power BI | Microsoft Learn

3 Check if the AWS PostgreSQL data source is configured to allow SSL connections. If SSL is required, make sure that the SSL certificate is valid and that the certificate chain is trusted by the machine running Power BI Service.

If none of these steps resolve the issue, you may need to query the backend logs from the PostgreSQL data source side to check the specific error message given for the further troubleshooting.

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
