Shiny app greys out



I host shiny apps on a virtual (e.g., server and everything works fine. Except for some colleagues that use windows computers with Kaspersky virus protection. I added a Godaddy SSL certificate to my apps, but the app still grays out.

Shinyapps hosted on work fine on all computer. Does anyone has a hint?


Assuming you’re using Shiny Server, did you check the app logs for what kind of error is occurring?
