Status code 500 : Container did not respond in time

Question

I would like to run an R Shiny application via Shinyproxy locally first.

My Application is functional, after docking it, it still works with a docker command.

I created a ‘shinyproxy’ image and launched the container but I get the following error message when I click on the application name:

# Error

**Status code:**  500

**Message:**  Container did not respond in time

I suspect a problem related to the different ports … notions that I don’t master.

The dockerfile of shiny app looks like :

with the following Rprofile :

local({
   options(shiny.port = 3838, shiny.host = "0.0.0.0")
})

The shinyproxy application.yml looks like :

What I tried is the following command :

docker run -d -v /var/run/docker.sock:/var/run/docker.sock --net sp-net -p 8080:8080 shinyproxy_container

All help is welcome
