Instability on shinyapps.io for recent deployment

I recently deployed versions of a simple Shiny application called shinycal to shinyapps.io. The app is constructed with the {golem} package and the repo is here While the majority of the time the app works just fine, I have seen certain times when the app simply fails to load (in fact it does not get passed the please wait loading indicator). Nothing shows in the log, and the only way I can get the app back to running is to manually restart the app in the dashboard. Are there some additional steps I can take to troubleshoot this?
