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).
ubuntu@ip-10-0-1-62:~$ jupyter notebook
