After JIRA has been upgraded, or configured for SSL, it is not able to be connected to, despite the process running.

The following appears in the Catalina log (for example catalina.2015-10-24.log):

  • JIRA is configured to use SSL, hosted by Tomcat.

Diagnostic Steps

  • If this exception is found in the logs it's highly likely this problem applies.


The Java Keystore (JKS) specified by Tomcat is in an invalid format. Tomcat by default expects it to be a JKS file, and this error can be thrown if it is a PKCS12 format (it's a bit like expecting a BMP and it's a JPG, in the image world).


It may be possible to tell Java to use the appropriate format - this can be done with the following:

  1. Stop JIRA.
  2. Add the JVM argument Djavax.net.ssl.trustStoreType=pkcs12 as per Setting Properties and Options on Startup.
  3. Start JIRA and test.

If this does not work, proceed to the Resolution.


Go back to the provider who supplied the key (either the CA vendor or appropriate department) and request for a Java Keystore (JKS) with the following in it:

  • A PrivateKeyEntry.
  • Any intermediate certificates, in the form of trustedCertEntry.

(info) It's recommend to host JIRA behind a reverse-proxy as as Apache or Nginx as per the below:
