I made a web page which includes seven shiny apps with a shinydashboard (actually it is the same app with different parameters by URL). But the apps are not displayed correctly, sometimes only the dashboard appears, but no plot output. Sometimes the iframe is just darkened out (e.g. looks like when a reconnect is neceassary). I tried a delayed loading of the iframes (with a timeout of three seconds), but the same result.
When I write the URL parameter to a file on the server side, I see that not all seven calls came through. But if a call comes through then I get my parameters right, but still the output does not appear.
Maybe it is a problem that I'am not using the RStudio Shiny Server Pro?
Thanks in advance
