Jupyter notebook won't connect to kernel

[bspiegel27]

I installed this extension and now my jupyter won't run anything as it can't connect to the kernel. Please advise on how I can troubleshoot/uninstall this extension. Thanks!

Sorry to hear that you're having trouble here. When you encounter the kernel connection issue described above, are there any error messages printed in the console where you invoked the "jupyter notebook" command?

The extension can be uninstalled by running:

jupyter serverextension disable --py jupyter_http_over_ws
pip uninstall jupyter_http_over_ws
