JupyterHub - oauth_client_id not found - oauth

Question

I am using Azure to run python notebook using Jupyterhub. After spinning up the VM, I was able to access the notebooks just by using my username and password (just like ssh). However, one day later when I switched to another network (I am not claiming that the network might have been a problem) I am unable to access the link. It gives me The site can't be reached error.
So I tried rerunning the process again, and since then I have been struggling to make it run again. I have searched for similar issues on GitHub, but they aren't helpful either.
After the kill the process using kill pid command, I tried running the jupyterhub through this command:
/anaconda/envs/py35/bin/python /anaconda/envs/py35/bin/jupyterhub-singleuser --port=50387 --notebook-dir="~/notebooks" --config=/etc/jupyterhub/jupyterhub_config.py
And it gives me the error:
JUPYTERHUB_API_TOKEN env is required to run jupyterhub-singleuser. Did you launch it manually?
So I searched through github issues similar to this. I tried generating token manually using:
jupyterhub token username
And I added that token to JUPYTERHUB_API_TOKEN via export JUPYTERHUB_API_TOKEN=token. I also added token:username to c.Authenticator.tokens in jupyterhub_config.py. Now I get this error:
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

ValueError: oauth_client_id cannot be empty.
I am not sure where I went wrong in this process. Anybody familiar with this issue?

Try running jupyterhub instead of jupyterhub-singleuser
For your specific use case, the command would be as follows:
sudo /anaconda/envs/py35/bin/python /anaconda/envs/py35/bin/jupyterhub --port=50387 --notebook-dir="~/notebooks" --config=/etc/jupyterhub/jupyterhub_config.py
Make sure that jupyterhub is installed (correctly) in the path you mentioned.
