I'm trying to set up a jupyterhub on my server and access it via an external network. I'm new on it so I'm using this repo as a starting point. I changed jupyterhub_config.py to use a Dummy authenticator.
The complete file looks like this:
import os
c = get_config() # noqa: F821
c.JupyterHub.spawner_class = "dockerspawner.DockerSpawner"
c.DockerSpawner.image = os.environ["DOCKER_NOTEBOOK_IMAGE"]
spawn_cmd = os.environ.get("DOCKER_SPAWN_CMD", "start-singleuser.sh")
c.DockerSpawner.cmd = spawn_cmd
network_name = os.environ["DOCKER_NETWORK_NAME"]
c.DockerSpawner.use_internal_ip = True
c.DockerSpawner.network_name = network_name
notebook_dir = os.environ.get("DOCKER_NOTEBOOK_DIR", "/home/jovyan/work")
c.DockerSpawner.notebook_dir = notebook_dir
c.DockerSpawner.volumes = {"jupyterhub-user-{username}": notebook_dir}
c.DockerSpawner.remove = True
c.DockerSpawner.debug = True
c.JupyterHub.hub_ip = "jupyterhub"
c.JupyterHub.hub_port = 8080
c.JupyterHub.cookie_secret_file = "/data/jupyterhub_cookie_secret"
c.JupyterHub.db_url = "sqlite:////data/jupyterhub.sqlite"
c.JupyterHub.authenticator_class = "dummy"
And I also changed the docker-compose.yml file to match the port I want to use for access. It looks like this:
...
volumes:
...
ports:
- "8787:8000"
environment:
...
...
Running the Docker container I can access the jupyterhub within my localhost and everything works fine. I can even tunnel the port 8787 from the server to another port on my computer via ssh and get the same results.
But when I try to access this port through the server's ip with a HTTP request, I get to see the login page, but I can't login. I tried different auth methods but none worked. It simply reloads the page and I don't get to start the server session. The docker produces no error in the log tho. It only said the user logged in, but nothing happens and the page just reloads. Here is the log file:

So, what should I do to be able to access it via my local machine?
Turns out it was my Chrome blocking the connection because it is insecure. I opened it on IE and it worked, so I configured a self signed SSL certificate to use on the server. Now I can use https protocol and Chrome lets me log in.
