Neo4j Graph Platform

Hi, I can't connect to the neo4j server currently today. What's wrong? I have restarted the server, however, it still does not work.

Neo.ClientError.Security.Unauthorized: The client is unauthorized due to authentication failure
  1. Do I need to set the security to false?
  2. how can I use it normally as before?
    Thanks

Perhaps try resetting the password for this database user? This page outlines some options: Password and user recovery - Operations Manual

Hi, how to change port 7474 of the browser to another port for example 9090, and port 7687 to another port?
Thanks
