IMS with HTTP, receives SSL error

Legacy Contributor

Hello!

I'm running the Infor provided Java-project for the IMS connector. 

When setting up the ION Messaging Service V3 in API Gateway I'm configuring the endpoint without HTTPS and without Enterprise Connector.

However, when I call the /ping endpoint I receive the following error:

I have a hard time understanding where the problem is.. My application is exposed and can be called in a regular browser towards the /ping endpoint, but I am not able to call it from API Gateway.
