Error in startServer(host, port, handlerManager$createHttpuvApp()) : Failed to create server

[Brunie White]

I am running Sleuth on Rstudio. I was able to load shiny with the sleuth_live(so) command. The data looked great. While i was attempting to save one of the graphs as an image, shiny and Rstudio closed. When relaunching Rstudio and executing the sleuth_live(so) command to launch shiny I get the following error:

> sleuth_live(so)

Loading required package: shiny

Listening on http://127.0.0.1:42427

Error in startServer(host, port, handlerManager$createHttpuvApp()) : 

  Failed to create server

Is someone familiar with this error? What can I do to resolve the issue?

I'm also getting the same error when trying to launch sleuth_live(so). Any chance you found a way to resolve the issue?
