OK follow up. I’m running my release in a docker container and specified the name like this:
-name <%= release_name %>@${HOSTNAME}
I started the app with REPLACE_OS_VARS=true and verified that the name was set correctly:
# vm.args
-name myapp@66277af8dc0e
But now when I connect from a different docker container (same network, same subnet) via:
iex --name debug --cookie 'secretcookie' --remsh myapp@66277af8dc0e
I get the error:
2017-08-19 18:57:25 Can't set long node name!
Please check your configuration
The same happens if I set the name via -sname:
#vm.args
-sname <%= release_name %>
