How to fix the "connection refused" exception in an IntelliJ plugin

I'm developing a plugin for IntelliJ (Community edition 15.0.3) from scratch.
Since the beginning I've had the exception below.

Hopefully some one can help me understand why I'm getting this warning and how I should fix it?

Error Message:

This exception comes from the IntelliJ Platform code, not from your plugin. There is nothing you can or should change in the code of your plugin to fix it.
