Grey screen on shiny with R Studio Server



Hello! I get a grey screen when using Shiny with my R Studio Server. I tried to downgrade shiny and httpuv, I updated R Studio to Version 1.1.453, and I tried different web browser and different hardware, but still got the problem.

This is my sessionInfo():

I appreciate your ideas!

I think I'm seeing the same issue, same version of R and RStudio Server running on RedHat 7. And the issue persists after publishing the app to RStudio Connect (w/ same version of R).
