Demo installation issue: useradm/auth/login error 404

I’m trying to install a demo 2.7.2 without success for the moment, a little help would not be refused.

During the demo script execution the following error occurs:

Failed to get the 'JWT' token from the useradm service.
This is needed in order to upload the demo Artifact.
curl exit code:  22
Retrying in 5...
Retried 5 times without success. Giving up.

In addition, deployments:mender is restarted in loop:

At first, I checked login has been well created, but I’m not able to use it:

      # Create a new user
      docker exec integration272_mender-useradm_1 /usr/bin/useradm create-user --username=mender-demo@example.com --password=ADE8120A2883

      # Try to login with the fresh user account
      curl -k -X POST -u mender-demo@example.com:ADE8120A2883 --fail --connect-timeout 5 https://localhost/api/management/v1/useradm/auth/login
      curl: (22) The requested URL returned error: 404

Do you have any idea to fix this issue?
