Can not Connect to Jupyter Notebook on AWS EC2 Instance

Question

I'm running Ubuntu 14.04 LTS on an AWS EC2 instance. I'm trying to connect to Jypter in Safari from my MacBookPro. I opened https port 443 and TCP 8888 in my security group.

ubuntu@ip-10-0-1-62:~$ netstat -a  | grep 8888 tcp        0      0 localhost:8888          *:*                     LISTEN      tcp        0      0 localhost:8888          localhost:36190         TIME_WAIT   ubuntu@ip-10-0-1-62:~$ netstat -a  | grep 443 unix  3      [ ]         STREAM     CONNECTED     12443     ubuntu@ip-10-0-1-62:~$  

I can't connect to Jupyter from my Safari browser on my Mac. (I can connect to Tensorboard on port 6006).

Answer 1

Okay, found the issue:

Edit your jupyter configuration:

jupyter notebook --generate-config  vim /home/ubuntu/.jupyter/jupyter_notebook_config.py 

Make sure that

c.NotebookApp.ip = '*' 

Also make sure you opened the relevant security group in your EC2 server (for example port 8888)

Run Jupyter:

jupyter notebook 

Now you can access it remotely with the right port
