How to Fix Power BI PostgreSQL Connection Error

Power BI allows users to connect to different data sources. However, while establishing a connection, users may encounter errors, one of which is the Power BI PostgreSQL Connection Error.

This error can be frustrating and confusing for users, especially if they are getting the error for the first time, and are not familiar with solving connectivity issues.

In this article, I will explore how to fix the Power BI PostgreSQL Connection Error and ensure you can establish a reliable and secure connection between Power BI and PostgreSQL databases.

Let’s get started.

Understand the Error Message

To fix the Power BI PostgreSQL Connection Error, it is important to take note of the error message, and what it means.

Typically, the error message reads “the remote certificate is invalid,” and this occurs when the SSL certificate presented by the remote server cannot be verified.

This can happen for different reasons, including an expired or revoked certificate, a mistake in the hostname and the certificate, or an issue with the certificate authority. By simply understanding the cause of the error, you easily take appropriate steps to fix it.

How to Fix Power BI PostgreSQL Connection Error

This error occurs for several reasons, and the error message usually indicates that Power BI was not able to connect to the PostgreSQL server, or the connection was lost while transferring data.

Luckily, there are several steps you can take to resolve this issue and establish a hassle-free and secure connection. Some of these steps include:

Check the SSL certificate

The first step in resolving the Power BI PostgreSQL Connection Error is to check your network connectivity.

Make sure that you are connected to the internet, and that your firewall is not blocking the connection. Also, try pinging the PostgreSQL server to confirm if you can access it

Update the SSL certificate

After checking for connectivity issues, and confirming that there are none, the next step is to check the PostgreSQL server settings.

So, ensure that the PostgreSQL server is running and listening to the correct port. To do this, login into the PostgreSQL server and check the postgresql.conf file. Also, check the credentials, and be sure that you are using the right connection server.

After updating the SSL certificate, you should be able to connect to PostgreSQL without encountering the error anymore.

Restart the PostgreSQL Server

If you are experiencing the “remote certificate is invalid” error in PostgreSQL, you can as well try restarting the PostgreSQL server.

This can help to refresh the SSL certificate and resolve any issues that may be causing the error. To restart the Postgres server, you can use the following command:

sudo service postgresql restart

This will stop and then start the Postgres server, letting you connect to it again. However, if the error persists after restarting the server, you can try out other solutions explained in this article.

Check Power BI Settings

Also, if the PostgreSQL server settings are correct, you may need to check your Power BI settings to confirm that you are using the right credentials to connect to the PostgreSQL server and that you have specified the correct server address and port number.

You can also check the Power BI logs to see if any error messages can help diagnose the issue.

Check SSL/TLS Certificate

Furthermore, if you are trying to connect to a PostgreSQL server using SSL/TLS, you should check the certificate used by the server.

Make sure that the certificate is valid and not expired. You can also import the certificate into Power BI to ensure that it is trusted.

Update Power BI

Finally, if you have checked for all the settings and confirmed that there are no network connectivity issues, the last option might be to update your Power BI Desktop to the latest version.

Updating Power BI can as well resolve compatibility issues and fix any bugs that may be causing the connection error.
