[TSBB2012nc]

Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

• Initial connection: I connect to the remote server from Machine A using VS Code Server and successfully run Jupyter notebook code.
• Disconnecting: I then disconnect from the remote server on Machine A.
• Subsequent connection: I connect to the same remote server from Machine B using VS Code Server.
• Kernel not found: When trying to run Jupyter notebooks on Machine B, the window keeps finding kernel

Running Jupyter locally or remotely?

Remote

[amunger]

Just to clarify, are you connecting to the remote machine with an ssh connection? (rather than just selecting a remote jupyter server kernel through the kernel picker)

Can you collect some logs for us:

1. set "jupyter.logging.level": "trace"
2. Repro the issue
3. copy the logs from the output panel after running Jupyter: Show Output and paste them here
