I recently setup a new server after we had to take down the old machine and I'm now trying to activate an app again that was running perfectly a year ago. The app is working fine if I run it from RStudio but immediately disconnects when I try to access it from the server although the app is displayed correctly as far as I can see).
No log files are created so I'm guessing that the R script is running fine and just terminating without an error. The Java console is giving me an 404 error for a font (awesome-font) that it isn't able to download. I only included awesome-font icons for a small menu and the icon are displayed there correctly. The error persists even if I use glyphicon for the icons or remove the icons altogether.
The app is available at http://188.8.131.52:3838/miREV/ and the error message was as follows:
This page uses the non standard property “zoom”. Consider using calc() in the relevant property values, or using “transform” along with “transform-origin: 0 0”. miREV

The application unexpectedly exited.
I'm guessing it could be a compatibility error between a fresh shiny server installation and an older app script but I cannot figure out what the problem is unfortunately. If anyone can give me a hint or point me to a solution, I would be very grateful.
