I launch our test suite from the IRIS terminal. I was demonstrating that the code used to create http requests is fairly generic and has worked previously. The subsequent individual tests on the IRIS server will test a variety of mocked endpoints, on both http and https ports on the Wiremock server. When tests are attempting to talk to any endpoint, on either http or https ports, the IRIS terminal returns the error which I posted.

I had already checked the SSL configuration from the management portal, and it is enabled on the IRIS server. The error persists, so I wanted to see if anyone else had the same issue.
