I have a shiny app which I am hosting on an AWS Ubuntu server. Suddenly, the session randomly crashes within about 1 minute of loading the app. It is not due to clicking any particular widget or selector.
The error I get in Network -> Response in the Firefox debugger is:
hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
c[2010,"Another connection still open"]
I'm not sure what the "hhh.." line is but it could provide a clue to someone, so I've included it.
Method: POST File: xhr_streaming
I have rolled back my app version and database to a prior working version, and the error still occurs.
This error does not happen locally, or when debugging RStudio on the server.
My shiny-server version is v1.3.0.403.
Other sockjs issues appear to be resolved with a newer version of shiny-server, but it looks like mine is fairly up-to-date.
Any help regarding further debugging would be much appreciated.
