Jupyter on EC2: SSL Error

Question

I\'m trying to serve a Jupyter notebook from EC2 but I\'m getting an SSL error. I\'m using this AMI: TensorFlow GPU - @nottombrown (ami-8ed4d0e4). I used a self

Answer 1

This error means that the SSL certificate can't be found.

If you haven't yet created an SSL certificate:

Create one by typing the following into the command line (starting at your home directory):

$ mkdir certs
$ cd certs
$ sudo openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout mycert.pem -out mycert.pem

(from these instructions)

Now that you have an SSL certificate:

You need to tell Jupyter where to find it.

Take a look at jupyter_notebook_config.py if you have one (or generate one using jupyter notebook --generate-config).

Make sure that you have the following line:

c.NotebookApp.certfile = u'/home/ubuntu/certs/mycert.pem' #location of your certificate file

(see the Jupyter Notebook docs)

and make sure that your self-signed SSL certificate is actually at that location. A common mistake is to mix up certs with .certs for example. A mistake like this will result in Jupyter not being able to find your SSL certificate and that'll result in the error that you're getting.
