I have the same problem. Now I notice this happening when I interrupt the program in vscode before closing the browser page. When doing that I have to wait a couple of minutes and restart the terminal again before it working again. So try to just close the browser page first and let the program stop by itself instead of manually stopping the program.

@tanhakabir this is likely related to the remote CLI

[thomassajot]

Experiencing the same issue. I installed jupyter using pip and conda.

Until @aeschli's fix goes into the next release, those encountering this with jupyter and forwarding a port (i.e. not running within VSCode via the python extension) can start the server without launching the browser:

jupyter-notebook --no-browser

Thanks @aeschli for the quick fix 😄
