Not able to log to jupyterhub notebook as admin

[Sireeshabotta]

My jupyterhub instance is running in a docker container. not able to login to the jupyterhub as admin. i created a user
adduser and provided the privileges to the user. but when i signed in to the jupytehub notebook the admin block is not available.

i even tired this, docker exec -it jupyterhub bash and then passwd root to set the password of root.
After that, i tried to login with the username "root" and password. However, root admin always returned "Spawn failed" error.
Only normal user which is created in docker container can get spawn successfully.

Did anyone know the solution?

I found myself in a similar situation although I did not try with a root user. The singleserver does not start for some users. All those users are part of the same Group. I created that goup to give access a service but that prevents the singleservers to be created. The panel for administration can be accessed in my case so it is somewhat different.

Just in case this might help someone, this is part of the logfile that I get:

jupyterhub | Common causes of this timeout, and debugging tips:
jupyterhub |
jupyterhub | 1. The server didn't finish starting,
jupyterhub | or it crashed due to a configuration issue.
jupyterhub | Check the single-user server's logs for hints at what needs fixing.
jupyterhub | 2. The server started, but is not accessible at the specified URL.
jupyterhub | This may be a configuration issue specific to your chosen Spawner.
jupyterhub | Check the single-user server logs and resource to make sure the URL
jupyterhub | is correct and accessible from the Hub.
jupyterhub | 3. (unlikely) Everything is working, but the server took too long to respond.
jupyterhub | To fix: increase Spawner.http_timeout configuration
jupyterhub | to a number of seconds that is enough for servers to become responsive.
