Failed to Save Files in JupyterLab

Symptom

When a file is saved in JupyterLab, an error message is displayed.

Possible Causes

• A third-party plug-in has been installed on the browser, and the proxy intercepts the request. As a result, the file cannot be saved.
• The runtime file in the notebook is too large.
• You have stayed on the Jupyter page for too long.
• There is a network error. Check whether a network proxy is connected.

Solution

• Disable the plug-in and save the file again.
• Reduce the file size.
• Open the Jupyter page again.
• Check the network.
