Description

I launch a Jupyter server with jupyter server --no-browser. Either right after the server successfully launches or after I connect to the kernel from a Notebook using Select Another Kernel > Existing Jupyter Server > Enter the URL of the running Jupyter server, I get a repeated wave of HTTP 403 errors at the terminal like below:

[W 2023-12-04 01:11:31.621 ServerApp] 403 GET /api/kernelspecs?1701670291555 (@127.0.0.1) 12.66ms referer=None

        raise web.HTTPError(403)
    tornado.web.HTTPError: HTTP 403: Forbidden

The error appears when working locally (on MacOS) or when SSH'd into a remote machine (using Linux) using the VS Code Remote Extension. I have tried changing jupyter_server_config.py to no avail:

c.NotebookApp.allow_origin = '*'
# c.NotebookApp.token = ''
c.NotebookApp.open_browser = False
c.NotebookApp.disable_check_xsrf = True

None of the above settings fix the issue. I would be most appreciative for your kind assistance.
