I copied the examples from the r-cran-shiny package (e.g. /usr/lib/R/site-library/shiny/examples/01_hello) to /srv/shiny-server and could (after restarting shiny-server (systemctl restart shiny-server)) access the application via firefox: http://localhost:3838/01_hello/ .

The only thing I could see is that both my sockjs scripts and the Debian ones are based on the same github version (https://github.com/sockjs/sockjs-node/releases/tag/v0.3.24), but the Debian version was generated with coffescript 2.7.0 and "my" version was generated with coffescript 1.12.7.

Sorry for pinging you again, but would you be able to take a look at this please?
I don't know enough coffeescript to be able to check this and it'd be
awesome if you could consider taking a look.
