I’m trying to set up a remote shell connection to an externally running node.
This node runs a release made using Distillery.
Rather than SSH-ing to the node and running /app/location/bin/appname remote_console, I want to run IEx locally, so that I can e.g. use :observer
However, running locally iex --name qqwy@Mycomputername --cookie mysecretcookie --remsh appname@12.34.56.78 returns the following unhelpful stack trace:
(Note: Since this is a live server with important data, I have replaced the real names, cookies and IP-address with placeholder ones.)

The cookie in my command matches the one set in the settings, and running /someplace/appname/bin/appname describe shows indeed this cookie, as well as the name appname@127.0.0.1.
What is going on?
