Gatling test: j.n.ConnectException: Unable to create Channel from class

Hi all,
I’m trying to run a Gatling simulation on an internal website and I’m running into the following error:
---- Errors --------------------------------------------------------------------

j.n.ConnectException: Unable to create Channel from class clas 10 (100.0%)
s io.netty.channel.socket.nio.NioSocketChannel

Do I need to do something with my Gatling HTTP SSL conf? I didn’t touch it because the server does not require a valid client side cert to establish a connection.
Thanks!
