Copy/paste this URL into your browser when you connect for the first time,
to login with a token:
    http://localhost:8888/?token=74e2ad76eee284d70213ba333dedae74bf043cce331257e0

Copying http://localhost:8888/?token=74e2ad76eee284d70213ba333dedae74bf043cce331257e0 and get

"can’t establish a connection to the server at localhost:8888." on Firefox,

"This site can’t be reached localhost refused to connect." on Chrome enter image description here

enter image description here

Further, jupyter notebook --ip=yy.yyy.yyy.yy --port=8888 gives

Traceback (most recent call last):
  File "/usr/bin/jupyter-notebook", line 11, in <module>
    sys.exit(main())

Solution

localhost will only work when trying to use jupyter (or well, anything) from the machine itself. In this case, it seems you're trying to access it from another machine.

You can do that with the switch --ip=a.b.c.d, where a.b.c.d is the public address of your EC2 instance (or using 0.0.0.0 to make it listen in all interfaces.)

You can also use --port=X to define a particular port number to listen to.

Just remember that your security group must allow access from the outside into your choice of IP/Port.

For example:

jupyter notebook --ip=a.b.c.d --port=8888
