TLJH login failures

I managed to get logged in to my TLJH server via the web browser. Played around with it and installed some packages via the terminal. However once I logged out it will not let me log back in again. JupyterHub is insisting I am entering the wrong username and password when the same username and password work via SSH.

Syslog states

Jul 9 19:32:47 jupyterhub python3[859]: [W 2018-07-09 19:32:47.993 JupyterHub base:503] Failed login for juan

Attempted solutions

• Checked /opt/tljh/config.yaml for problems, appears intact with contents

users:
  admin:
    - juan

• Restarting server software didn’t help.
• Restarting the VM entirely didn’t help.
• Changing user password from the command line and trying the new password didn’t help.
• Changed web browsers, it didn’t help.

So I have the login page, but it is not recognizing the account. This suggests a serious potential problem with how JupyterHub is authenticating, since it appears to have broken.

I have the same problem, but can’t find the file /opt/tljh/hub/state/passwords.*, is there any other solution to reset the password of a admin user when login failed?

I was wondering why this is closed. The problem persists, at least in my case.
