Pkix Path Building Failed Minecraft (Solution)

When trying to connect to a Minecraft server, a common problem known as Pkix path construction failed minecraft may appear.

Simply put, the error happens when the Java framework doesn’t check the SSL certificate of the download URL that Minecraft requests.

There are a few ways to correct this error, but before attempting to do so, it is crucial to know why it occurs.

What Causes The Pkix Path Building Failed Error

The Java framework failed to check the SSL certificate of the URL that Minecraft requested, which prevented it from downloading the file and caused the error “pkix path construction failed” in the game.

Any Java application trying to visit an HTTPS URL will first test if it is familiar with the domain’s certificate, regardless of whether it is a third-party library, a build process, or even custom code.

The domain’s certificate is compared against a list that Java internally keeps achieving this. This list is known as a trust store.

The trust store, which also protects against client system incursions that may emanate from such hostile entities, enables Java to terminate connections to any rogue URL.

The obvious extension of this behavior is that any URLs that use a self-signed certificate will have problems. This is because a self-signed certificate will never be added to the Java trust store until it is explicitly added.

How, though, could libraries or other software applications that try to visit well-known domains encounter this error?

Usually, this is caused by a corrupted trust store on your Java client system.

This could happen due to an improper installation or a failed update attempt. But until the trust store is updated, your Java client programs won’t be able to connect to HTTPS URLs.

Let’s examine the solution now:

How To Fix Pkix Path Building Failed Minecraft Error

You must download the server certificate for the URL that Minecraft is attempting to access and add it to the Java Trust Store to resolve the Pkix path building failed Minecraft error.

The first step is to determine whether your network configuration or firewall rule is to blame for the Java issue. Try loading the URL in error to rule out this possibility.

If the browser loads it without any issues, the problem is with the client application’s certificate setup.

Follow these steps to fix it:

Step 01 – Download The Certificate Manually

The server certificate for the URL that needs to be downloaded must first be downloaded.

Either the command prompt or the browser can be used to accomplish this. To manually add the certificate to the trust store, this is done.

Although there will typically be a certificate chain and intermediate CAs, the downloaded certificate is frequently the root certificate.

Use the following command on an admin command prompt to download the certificate if you don’t want to use a browser:

openssl s_client -showcerts -servername [DOMAIN] -connect [DOMAIN]:443

The output, which includes all of the certificates in the chain, will appear as follows:

Copy every certificate into a separate file with a different name. Your files must contain both the BEGIN CERTIFICATE and END CERTIFICATE sections.

Step 02 – Add The Certificate To Java Trust Store

The internal Java trust store can now be updated with the newly downloaded certificates. This can be done by using the Keytool utility.

The JRE trust store’s default password is “change it.” Make sure you’re using the correct password if you’ve changed it.

Make sure that each certificate’s alias name is distinct.

Step 03 – Confirm The Certificates

Use the following command to verify that the certificates have been added after you have imported them.

keytool -list -keystore "/usr/local/java/jdk1.8.0_60/jre/lib/security/

Step 04 – Restart Minecraft

Restart Minecraft now. This time, if all the steps are followed correctly, there shouldn’t be any pix path-building failed errors.

Bottom Line

Although dealing with the Pkix path construction failed Minecraft error can be irritating, it is fixable. After manually downloading and importing the server certificates, you should be good to go.
