Hi,
I am using RStudio, which is an IDE for the R language, and the 'citr' addgin for RStudio, which links to Zotero, a reference manager, to provide access to references and make bibliographies in R markdown documents. citr uses shiny, a web app for the R language. I have exactly the same problem with the 'reprex'
addin.

Using these two addins involves connecting to a web-server which runs on http://127.0.0.1:3680/ This url works fine in my browser, and brings up the correct interface. However, within RStudio it fails with the following error shown in a popup window within RStudio :-

Code:
Connection closed
  Failed to load URL http://127.0.0.1:3680/.
  QtNetwork Error 2


I've looked for this error code with no success. I suspect the solution is some error on my part in configuring QT, or RStudio. QTnetwork has the 'networkmanager' and 'ssl' use flags set, and 'libproxy', 'connman' and 'sctp' flags unset. I'm not sure where to start looking.

Any advice gratefully received.
Thanks,
Anthony Staines
