Hello everyone,

I use shinyproxy 2.02,

Some people have a gray screen when they try to connect to the app. In shinyproxy.log, i find this error:

Has someone already had this problem ?

Thank,

Hi,

I find something perhaps similar happening in my app (but only when accessed through shiny proxy, not when run directly in the Docker container).

It starts up fine, bit when clicking around in an interactive DT::datatable it will suddenly disconnect.

And the R log has no errors.
