I would greatly appreciate any feedback about a ‘Not Found’ error I get when deploying a Flexdashboard Shiny app (‘runtime: shiny’) to the shinyapps.io server. I'm actually having trouble deploying any similar app to shinyapps.io now, whether my own app or a basic example such as this one. The difficult bit is that I don't get any errors in the logs, and the only sign is the printing of 'Not Found' (in bold, at the top left of the screen) on the browser after the erroneous deployment has completed.
Local deployment is perfect, and moreover the same app was successfully deployed to shinyapps.io just a few hours ago.
I have updated all programs and packages. Also, my server hours are still fine, so I can't find any reason. I encountered plenty of different errors before, but never this one.
Thank you very much in advance
