Jupyter notebook and Google colab connection error

So i’m trying to set up a local host to run a google colab project with jupyter. I start the server, and the backend url it supplies loads in chrome, but when I put it in google colab, the request gets blocked with the error message “[W 2021-09-04 05:20:18.715 ServerApp] 404 GET /http_over_websocket?min_version=0.0.7&jupyter_http_over_ws_auth_url=http%3A%2F%2Flocalhost%3A8888%2Flab%3Ftoken%3D6dd9a3cb1f9404354b3354d94654b68c76bbf33cd95245e3 (::1) 1.00ms referer=None” How can I fix it and get it to connect to google colab?
