This is the first time I've created an R notebook on my new installation of DSS. I created an R notebook. When I tried to open it, I got a 502 Bad Gateway error. I know R is at least minimally working because I've already run an R recipe successfully. Any thoughts on what is causing the 502? Maybe something with the Jupyter server?
"502 Bad Gateway" is the standard HTTP error that indicates "I am a proxy, and the server I was supposed to proxy to wasn't responding". Here, this error is thrown by the nginx proxy that sits in front of all processes of DSS. Therefore, the error indicates that the IPython server wasn't running. You might have some information in DATA_DIR/run/ipython.log
