  <p>Can anyone help me out?</p>
  
  <p>I am using MongoDB version 3.4.4.</p>
  
  <p>Please and thank you.</p>
  
  <p>In the Mongodb Log, it says that</p>
  
  <p>SCRAM-SHA-1 authentication failed for usernameexample on Grandnode from client 111.111.111.111:12312 ; UserNotFound: Could not find user usernameexample@Grandnode</p>
  
  <p>but Grandnode is the database name that I want to create in Grandnode project.</p>
  
  <p>How to solve this problem?</p>
