Google colab websockets cannot assign requested address

Question

My colab notebook outputs this error:

OSError: [Errno 99] error while attempting to bind on address ('::1', 8080, 0, 0): cannot assign requested address

code

This error seems to happen on any port I set it too.

Links I have tried:
