SSL error running Jupyter Notebook on Google Cloud VM

Question

I've set up an instance on a GCP virtual machine and have installed anaconda, torch, etc. and have initialized my Jupyter notebooks (including the config setup). I've mounted my Google storage bucket and everything seems to be okay, except that when I run Jupyter:

~$ jupyter notebook --certfile=/home/username/certs/mycert.pem
[I 16:18:41.293 NotebookApp] [nb_conda_kernels] enabled, 3 kernels found
[I 16:18:44.879 NotebookApp] Serving notebooks from local directory: 
/home/username
[I 16:18:44.879 NotebookApp] 0 active kernels 
[I 16:18:44.879 NotebookApp] The Jupyter Notebook is running at: 
https://0.0.0.0:8888/
[I 16:18:44.879 NotebookApp] Use Control-C to stop this server and shut 
down all kernels (twice to skip confirmation).

I can access it on my VM's external IP:

https://xx.xxx.xxx.xx:8888

But as soon as I do that, I get this error:

ssl.SSLError: [SSL: SSLV3_ALERT_CERTIFICATE_UNKNOWN] sslv3 alert 
certificate unknown (_ssl.c:645)

Full traceback:

This is on a Linux VM. Locally, I'm on a PC. I've already tried rewriting the config file for Jupyter but I'm stuck on this problem. None of the solutions I've found online have worked.

It seems like you're trying to manually setup a VM instance with Jupyter. That tends to be pretty tricky, have you considered using GCP's AI Platform Notebook instead? https://cloud.google.com/ai-platform-notebooks

It gives you a VM with Jupyter Lab and many popular DL/ML libraries preinstalled and configured and you don't even need SSH to access your notebook.
