Fresh Shiny Server installation problems: Starting listener on http://[::]:3838

I have developed a shiny app using RStudio. I now want to make this available to my work colleagues. So I have installed Shiny Server open source edition. I am running Ubuntu 18.04.1 LTS I have followed the instructions here: Immediately after running sudo gdebi shiny-server.deb, the instructions says Shiny Server should now be installed and running on port 3838 . You should be able to see a default welcome screen at http://your_server_ip:3838/ . However, when I point my browser there, the welcome screen appears but the test apps on the right side do not run, and instead show: " An error has occurred .The application failed to start. The application exited during initialization…

I am facing the same issue on RedHat 6 as the topic thread above,
I can open the Shiny server webpage but not able to execute sample "hello" program. Did you get any solution for this if yes please share ?

Thanks in advance.
