@weiqinwang Did you ever find a solution?

[Jane333]

I solved that same error (which I got running a different .ipynb file inside a different docker container) by explicitly providing the IP address (note that 'localhost' did not work):

jupyter notebook --ip='127.0.0.1'

[phizaz]

@Jane333 Addition to that, I can also use --ip=*

[snth]

For me only the --ip=* version worked.

[monajalal]

jupyter notebook --ip='127.0.0.1' worked for me!

[EvgeniaAR]

worked for me too :) Could you provide a short explanation why specifying an IP address resolves this issue?

[phizaz]

@EvgeniaAR honestly, no idea - -" you might need to dig deeper to what "address" it is trying to allocate.

jupyter seems to try to start the webserver on localhost in my case there was no entry in the hosts file (I don't know why). As soon as I added 127.0.0.1 localhost to my hosts file it worked again

[musger]

I am having the same problem and I can work around it with --ip=127.0.0.1 Note that localhost does not work for me although I have the 127.0.0.1 localhost entry in my hosts file.

This problem started coming in my Dockerized jupyter notebook. Workaround was to start the notebook with --ip=<actual_IP_of_container>, which I obtained by popping out of docker container using ctrl+p+q and then finding out ip with docker container inspect <container_id>. This dumped plethora of information along with IPAddress field.

Then to start notebook the command became: jupyter notebook --ip=<IPAddress> --allow-root
