I installed the shiny-server on a Ubuntu 16.04.1 and according to the console output it is active and running:
systemctl status shiny-server
● shiny-server.service - ShinyServer
Loaded: loaded (/etc/systemd/system/shiny-server.service; enabled; vendor preset: enabled)

Then I opened the port 3838 as stated in the installation guide:
netstat -ntlp | grep LISTEN
(Not all processes could be identified, non-owned process info

Howevever if I try to access my server over the port 3838 in a browser, I don't get any response from the server and the site stays blank and eventually times out.
Any ideas what I might be missing?
Apparently there was some problem with the port 3838 on my server. Although the console output above states that it is open and listed as "LISTEN", it still didn't work. When I changed the default port for my shiny-server in the configuration file (/etc/shiny-server/shiny-server.conf) to 80, it suddently worked:
# Define a top-level server which will listen on a port
server {
# Instruct this server to listen on port 3838
listen 80;
