Troubleshooting jupyterhub - ubuntu server 18.04 LTS

JupyterHub

Hi, I have successfully installed jupyterhub in my ubuntu server.

Jupyterhub is listening … screen shot

sk@dzlenovo:/etc$ sudo jupyterhub
…
[I 2022-01-16 02:44:26.834 JupyterHub app:3084] Hub API listening on http://127.0.0.1:8081/hub/
02:44:26.837 [ConfigProxy] info: 200 GET /api/routes
…

This machine IP is 192.168.1.75 and hence when I use url http://192.168.1.75:8081/hub/ I get the following message in the browser. Any tips to troubleshoot?

Is that port open on your remote machine’s security?
Are you connecting to it on a network that has that port allowed? My institution’s firewall commonly blocks a ton of stuff on the web, and so I have to use ssh tunnel to connect when I am at work. From home, I can connect directly without needing ssh tunnel to bridge.
