Remote jupyterhub kernel fails to launch: "waiting for kernel to be idle"

See original GitHub issue

Environment data

  • VS Code version: 1.67.2, 1.68.1
  • Jupyter Extension version (available under the Extensions sidebar): 2022.4.1021342353, 2022.5.1001601848
  • Python Extension version (available under the Extensions sidebar): 2022.8.1
  • OS (Windows | Mac | Linux distro) and version: OSX 12.4
  • Python and/or Anaconda version: various 3.7-3.9
  • Type of virtual environment used (N/A | venv | virtualenv | conda | …): conda
  • Jupyter server running: Remote

Expected behaviour

Remote kernel successfully launches

Actual behaviour

Sits at “Connecting to kernel: Waiting for Jupyter Session to be Idle”

Steps to reproduce:

  1. Select remote URI via “Jupyter: Specify Jupyter Server for connections”
  2. Highlight a cell in file, right click and select “Run in interactive window”
  3. Get message that kernel is starting, then see “kernel failed to launch in time” after timing out

This seems similar to https://github.com/microsoft/vscode-jupyter/issues/9014

Everything worked fine until this morning - I tried downgrading VS Code, the Jupyter extension, the Python extension, no dice. This is on my M1 laptop using the arm build; old Intel MBP running VS Code 1.67.1, jupyter extension v2022.4.1021342353, and python extension v2022.8.1 still works.

The log is kind of confusing - it’s like it’s trying to launch a local and remote server simultaneously? Looking at the kernels on the remote server, it’s certainly talking to it, as it launches a kernel I can see in the web UI when I interact with VS Code. Just fails the waiting for idle…

Please let me know if there’s any other logs or diagnostics that’d be helpful!
