Working on deploying a Shiny App on my own domain through a Digital Ocean using Ubuntu.
After completing all the installation procedures I can access the :3838 port fine and that is displaying the welcome to shiny server page just fine, as well as the :3838/sample-apps/hello page also working as planned however when i try and bring up my own app that has been loaded onto the server I get an error warning saying that the "The application failed to start." and that "The application exited during initialization."
When I look a little deeper into the logs it brings up the following however I have yet to be able to find a solution.
Warning in readLines(file, warn = FALSE) : cannot open file '/srv/shiny-server/ESapp/global.R': Permission denied Error in readLines(file, warn = FALSE) : cannot open the connection Calls: runApp -> -> sourceUTF8 -> readUTF8 -> readLines Execution halted
Any advice would be much appreciated.
