ReadyAPI - JIRA integration: Single Sign-On

Hello, I am exploring an option to connect to JIRA from ReadyAPI (1.9.0) using JIRA plugin. Currently JIRA is setup to use single sign on via OKTA. Providing windows credentials in plugin doesn't work. Any pointers or suggestion how to make it work?

ReadyAPI log shows below error when clicking JIRA icon:

ERROR:java.lang.RuntimeException: javax.net.ssl.SSLHandshakeException: General SSLEngine problem
