Question

Answer 1

James023 already stated the correct answer. Just formatting it

if you have not configured jupyter_notebook_config.py file already

Step1: generate the file by typing this line in console

jupyter notebook --generate-config

Step2: edit the values

gedit  /home/koushik/.jupyter/jupyter_notebook_config.py

( add the following two line anywhere because the default values are commented anyway)

c.NotebookApp.allow_origin = '*' #allow all origins

c.NotebookApp.ip = '0.0.0.0' # listen on all IPs

Step3: once you closed the gedit, in case your port is blocked

sudo ufw allow 8888 # enable your tcp:8888 port, which is ur default jupyter port

Step4: set a password

jupyter notebook password # it will prompt for password

Step5: start jupyter

jupyter notebook

and connect like http://xxx.xxx.xxx.xxx:8888/login?

Answer 2

The other reason can be a firewall. We had same issue even with

jupyter notebook --ip xx.xx.xx.xxx --port xxxx.

Then it turns out to be a firewall on our new centOS7.

Answer 3

I got the same problem but none of workarounds above work for me. But if I setup a docker version jupyter notebook, with the same configuration, it works out for me.

For my stituation, it might be iptables rule issues. Sometimes you may just using ufw to allow all route to your server. But mine just iptables -F to clear all rule. Then check iptables -L -n to see if its works.

Problem fixed.
