Error when trying to load shiny app: "This site can't be reached" (Shiny Server 1.4.4)

[Isaac Petersen]

I just tried to install Shiny apps on our DigitalOcean server. After installing R, the Shiny package, and Shiny Server v1.4.4.801 according to these instructions (https://www.rstudio.com/products/shiny/download-server/). I get the following error when trying to navigate to my shiny app in a browser (http://fantasyfootballanalytics.net:3838/Stocks/): "This site can’t be reached".  I verified that I can access the main domain, so I'm not sure what's going on.  I tried stopping and restarting the shiny server, but that didn't solve it.  My app is located in: /srv/shiny-server/Stocks/app.R

Here's my shiny-server.conf file:

----------------------------------------------------

# shiny-server.conf

env LANG='en_US.UTF-8'

description "Shiny application server"

start on runlevel [2345]

stop on runlevel [016]

limit nofile 1000000 1000000

post-stop exec sleep 3

post-start script

    i=0

    while [ $i -lt 5 ]

    do

        pgrep "shiny-server" || exit 1

        sleep 1

        i=$((i+1))

    done

end script 

  

exec shiny-server --pidfile=/var/run/shiny-server.pid >> /var/log/shiny-server.log 2>&1

respawn limit 3 30

respawn

Any help would be greatly appreciated, thanks!
