Use SSLPoke to verify connectivity. Try the Java class SSLPoke to see if your truststore contains the right certificates. This will let you connect to a SSL service, send a byte of input, and watch the output. Download SSLPoke. Execute the class as per the below, changing the URL and port appropriately.

If Djavax. net. Store is present in your JVM arguments, Java will use the keystore specified with that argument. You can verify whether the Djavax. Store parameter is causing problems by running the SSLPoke test and specifying the same JVM argument to use that keystore. For example JAVAHOMEbinjava Djavax. Storemycustomtruststore SSLPoke jira. If this fails confirming the problem that the truststore doesnt contain the appropriate certificates, then the certificate will need to be imported into that truststore as per the instructions in Connecting to SSL Services. Cause. Whenever Java attempts to connect to another application over SSL e. HTTPS, IMAPS, LDAPS, it will only be able to connect to that application if it can trust it. The way trust is handled in the Java world is that you have a keystore typically JAVAHOMElibsecuritycacerts, also known as the truststore. This contains a list of all known Certificate Authority CA certificates, and Java will only trust certificates that are signed by one of those CAs or public certificates that exist within that keystore. For example, if we look at the certificate for Atlassian, we can see that the . Digi. Cert High Assurance EV Root CA and Digi. Cert High Assurance CA 3. These intermediate certificates have been signed by the root Entrust. Secure Server CA These three certificates combined are referred to as the certificate chain, and, as they are all within the Java keystore cacerts, Java will trust any certificates signed by them in this case,  Alternatively, if the  Java would also trust that site. This problem is therefore caused by a certificate that is self signed a CA did not sign it or a certificate chain that does not exist within the Java truststore. Java does not trust the certificate and fails to connect to the application. Resolution. Make sure you have imported the public certificate of the target instance into the truststore according to the Connecting to SSL Services instructions. Make sure any certificates have been imported into the correct truststore you may have multiple JREJDKs. See Installing Java for this. Check to see that the correct truststore is in use. If Djavax. net. Store has been configured, it will override the location of the default truststore, which will need to be checked. Check if your Anti Virus tool has SSL Scanning blocking SSLTLS. If it does, disable this feature or set exceptions for the target addresses check the product documentation to see if this is possible. If connecting to a mail server, such as Exchange, ensure authentication allows plain text. Verify that the target server is configured to serve SSL correctly. This can be done with the SSL Server Test tool. If all else fails, your truststore might be out of date. Upgrade Java to the latest version supported by your application.
