Jupyterhub with Kubespawner: Redirect loop detected

Question

I am trying to create Jupyterhub from python libraries. After providing the configuration, when i am logging in i am getting Redirect Loop Detected error.

Jupyterhub Image content: Dockerfile:

FROM xxxxx/openjdk11

RUN microdnf update -y
RUN microdnf install -y python3 python3-pip python3-setuptools python3-wheel nodejs pam

RUN npm install -g configurable-http-proxy

RUN pip3 install --upgrade pip
RUN pip3 install jupyterhub jupyterlab jupyterhub-kubespawner

RUN jupyterhub --generate-config
COPY files/jupyterhub_config_custom.py .

RUN cat jupyterhub_config_custom.py >> jupyterhub_config.py

EXPOSE 8080
ENTRYPOINT ["jupyterhub"]

jupyterhub_config_custom.py:

c.Authenticator.admin_users = {'admin'}
c.DummyAuthenticator.password = 'pass'
c.Authenticator.allowed_users = {'admin'}
c.NotebookApp.allow_root = True
c.Spawner.port = 8080
c.Spawner.default_url = '/lab'
c.JupyterHub.authenticator_class = 'dummy'
c.NotebookApp.allow_origin = '*'

c.JupyterHub.spawner_class = 'kubespawner.KubeSpawner'
c.KubeSpawner.image = 'sigleuser-image'
c.KubeSpawner.start_timeout = 600

c.KubeSpawner.port = 8000
c.JupyterHub.base_url = '/'

After login is am getting 500 Internal Error. Redirect Loop Detected. Really need help with this. Logs: Jupyterhub Pod:
