Scale up as you grow — whether you're running one virtual machine or ten thousand.

From GPU-powered inference and Kubernetes to managed databases and storage, get everything you need to build, scale, and deploy intelligent applications.

I have set up Rstudio and shiny servers. Both seemed to be working OK (the demo apps work and I can log into & use Rstudio from a browser). But now I have two (possibly related?) problems:
In Rstudio, I get this error “127.0.0.1 refused to connect” whenever I try to run a Shiny app or even try to open a help page. (e.g. ?runApp, or ?mean).
I copied an existing shiny app to /srv/shiny-server/. It worked fine at first, but after I made some changes (on a local version of R) and replaced the files on the server, I get this error when trying to launch the app:
An error has occurred The application failed to start. The application exited during initialization.
Warning in readLines(file, warn = FALSE) : cannot open file ‘/srv/shiny-server/SMP_shinyapp/global.R’: Permission denied Error in readLines(file, warn = FALSE) : cannot open the connection Calls: runApp -> <Anonymous> -> sourceUTF8 -> readUTF8 -> readLines Execution halted
I am very new to using servers, ubuntu etc. I got as far as I did by following tutorials and googling stuff, but now I am completely stuck. Any advice would be greatly appreciated!
