Hello, I'm running Jupyter behind a reverse proxy. I noticed in the UI that the kernel would periodically get killed and recreated, and found it was due to the proxy killing idle websocket connections. I increased the proxy's idle timeout and the errors went away.
However I did some research and found that Jupyter SHOULD be sending periodic pings to keep websockets alive, based on this code anyway: https://github.com/jupyter/notebook/blob/master/notebook/base/zmqhandlers.py#L88 This doesn't seem to be happening in our case. I tried playing with the `ws_ping_interval` setting but it doesn't seem to have any effect. Any ideas why websocket pings wouldn't be happening, or how to debug this further? I'm running Jupyter 4.4.0 FWIW. Thanks, Rob -- You received this message because you are subscribed to the Google Groups "Project Jupyter" group.
