Shiny apps all blank except for "Not Found" when loaded in browser

[Rob S.]

Just installed built & installed Shiny Server on GNU Linux, got it to run, but whenever I navigate to my app in a web browser while shiny-server is running, I get the same thing, no matter which app it is--just a blank page with two words in h1-level text: "Not Found".

I have no idea where to begin here, since this obviously isn't a very descriptive error message and I don't see anything wrong in the apps themselves; one of them is simply the "hello" sample app that comes with Shiny. I'd be grateful for any advice on what to do to start tackling this.

(I should also probably note that this "Not Found" is NOT the site's standard 404 error page)

Rob,

Could you please provide the following info:

- Version of Shiny Server (shiny-server --version)

- Copy of your /etc/shiny-server/shiny-server.conf file

- The directory structure of where you have your applications 

- The URL you are using to access your application(s)

- Also, if you see any errors in the /var/log/shiny-server.log file

Thanks,

Fereshteh
