ECONNRESET Error With Multiple Runner Sessions

Running a Collection continuously on Windows Server 2016. Starting one Runner session it seems to work fine over and over. As soon as I start a second Runner session I begin to see the following example error.

Doing this same process under Windows 10 I do not see the error even with up to 5 concurrent sessions.
