Cannot run Jupyter on AWS EC2 Browser says "Site can't be reached"

Question

I have set up an AWS account on their free tier and after installing Anaconda and Jupyter Notebooks I am unable to connect to Jupyter notebooks through my browser. I get the below screen:

The process I have gone about t set this up is mostly summarised at the link below:

https://medium.com/@josemarcialportilla/getting-spark-python-and-jupyter-notebook-running-on-amazon-ec2-dec599e1c297

There are a few changes I have made to the above medium article process due to it not working. The main one is that my certificate has the below commands in it

# Configuration file for jupyter-notebook.

c = get_config()



# Notebook config this is where you saved your pem cert

c.NotebookApp.certfile = u'/home/ubuntu/certs/mycert.pem'

# listen on all IPs

c.NotebookApp.ip = '0.0.0.0'

# Allow all origins

c.NotebookApp.allow_origin = '*'

# Don't open browser by default

c.NotebookApp.open_browser = False

# Fix port to 8888

c.NotebookApp.port = 8888

Everything seems to go as expected until I get to typing the necessary link in the browser. When I type Jupyter notebooks into my console I get the below (X's are alpha- numerics I don't think I should share):

[I 07:28:56.291 NotebookApp] Writing notebook server cookie secret to /run/user/1000/jupyter/notebook_cookie_secret
[I 07:28:57.297 NotebookApp] JupyterLab extension loaded from /home/ubuntu/anaconda3/lib/python3.7/site-packages/jupyterlab

[I 07:28:57.299 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 07:28:57.303 NotebookApp]

To access the notebook, open this file in a browser:
file:///run/user/1000/jupyter/nbserver-29637-open.html
Or copy and paste one of these URLs:
https://(ip-XXX-XX-XX-XXX or XXX.X.X.X):8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

In the browser as well as typing what the tutorial says:

https://XXX-X-XX-X-XXX.us-east-2.compute.amazonaws.com:8888

I have also tried the below:

https://XXX-X-XX-X-XXX.us-east-2.compute.amazonaws.com

https://(ip-XXX-XX-XX-XXX or XXX.X.X.X):8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

https://ip-XXX-XX-XX-XXX:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

https://ip-XXX.X.X.X:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

None of these seem to work.

If anyone has any suggestions it would be greatly appreciated.

Thanks

Edit

After recreating the instance and this time putting the security setting to All Traffic rather than just SSH (Thanks to Lamanus) the browser now just continually trying to connect while the console gives the the output below:

Answer 1

I worked it out with some help from Lamanus.

As i said in my edit I had to recreate my instance making sure to change the security settings from SSH to All Traffic.

Then the next time I activated my terminal I had to go to the certs folder and modify some of the certificates with the below commands:

cd certs

sudo chmod 777 mycert.pem

After that I went to a screen where it asked me for a token. The one I provided was the token the console provided me on the end of the below

https://ip-XXX-XX-XX-XXX:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

So I copied and pasted the xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx part into the token area.

Thanks
