Web Interface Login (GraphAcademy Start)

Hi,
I am running through the basic intro training.
In tutorial video "Getting Started with Neo4j Browser" the access to the Browser is done by the web interface (localhost:7474). When I am opening this in Chrome, I am asked to perform ":server connect."
But my normal neo4j account login credentials do not work:
Neo.ClientError.Security.Unauthorized: The client is unauthorized due to authentication failure.
What am I doing wrong?

Thanks in advance for help!

Kind regards,
Falko
