I have a RStudio Server (OS) behind an apache reverse proxy which I am using for collaborative development with a client. Most of the time things are working fine, in particular running Shiny applications and the terminal, which are sometimes difficult behind a reverse proxy, work without problems.
However, there are difficulties when running an R Markdown document with shiny backend, i.e. a document with

in the YAML header. Such documents work fine for me with a direct internet connection to the server using current FF. For my client, who has to use a corporate proxy with IE 11, these do not work. On running such a document with the "Run document" button he sees

in the "R Makrdown" tab, but after that the process stalls. In particular there is no progress output from
Any idea how to debug this? Could it be that the corporate proxy filters out something?
