Cannot start euler's app

Hi everybody,
I’m having problem launching the euler’s app on ShinyProxy.
I can build the docker image without problem, and if I run it directly on Docker using the command:

docker run -it -p 3838:3838 openanalytics/shinyproxy-template

the apps works normally.
However, when I try to run it on shinyproxy I get the following error:

Status code: 500

Message: Failed to start container: java.util.concurrent.ExecutionException: org.apache.http.conn.HttpHostConnectException: Connect to localhost:2375 [localhost/, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect

I’m using Docker Toolbox on Windows 10. The docker’s daemon runs at IP

You probably need to configure docker start-up options, as described in This page seems to provide instructions on docker configuration in Windows 10.
