WebSocket is already in closing or closed state - Jupyter time out error.

[pr334]

Hello Everyone,

I launched a Sagemaker notebook instance in my customer AWS environment and was working on Jupyter terminal in chrome browser. When my Jupyter terminal is left idle for few minutes, the session gets hanged. On Seeing the console tab in Dev tools its showing the error message - " WebSocket is already in closing or closed state". On refreshing the browser it gets active again. Fortunately I'm not seeing this scenario happening in JupyterLab.

I'm sot sure how to fix this issue in Jupyter. Could anyone please help me in fixing this ?

Thanks, Praveen.
