jupyter notebook - Why `tornado.web.HTTPError: HTTP 403: Forbidden`?

59 views Asked by At

I'm trying to run Isaac Sim in jupyter notebook, but it worked before, and now it's broken. So I think this error is more general than only there.

When I start jupyter notebook --MappingKernelManager.default_kernel_name="Isaac Sim Python 3" $@ || error_exit I get the following output.

It looks ok at the start, but then, after printing the links "To access the server in the browser", it starts spamming the same tornado error (very quickly, on millisecond scale), while incrementing the number in 403 GET /api/kernels?1711376170026

The browser opens fine, and I can run the kernel there. These errors not always happen! I don't know why they happen. One time I can run the command and everything is fine; another time I repeat the same initial conditions - and can't get rid of the errors..

  1. It's impossible to get the links "To access the server in the browser" because they disappear from the terminal so quickly due to the flood of tornado errors below.
  2. I'm worried I broke something on my system..

What could be the reason?

I have Ubuntu 22.04 with 2 users.
