Symptoms

After turning on HTTPS connection in FlexNet License Server Manager (FLSM) and trying to access the Devices or Reservations tab from the menu, the screen shows the following error:

"PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException"

Diagnosis

The given error suggests that Java does not trust the certificate, therefore FlexNet License Server Manager fails to connect to the server application (Local License Server).

Solution

To resolve this, add the server side certificate to the Java truststore on the system where the FlexNet License Server Manager application is running.

Below is the sample command that will help to add the required certificate to the Java truststore:

Export alias certificate from the keystore:

keytool -export -alias [alias_name] -keystore keystore.jks -rfc -file server_cert.certs

Import certificate to the Java truststore on which the application is running:

keytool -import -trustcacerts -keystore [java_path]/lib/security/cacerts -storepass [password] -alias [alias_name] -import -file server_cert.certs

Once the required certificate is imported to the Java truststore, the https connection should be successful to the Local License Server from FlexNet License Server Manager application.
