title: using mongodump with mongodb atlas
body: <p>For some reason I cant connect to atlas using the connection string but instead of using mongo use mongodump. I have tried all type of string. </p>
  
  <p>So its either I get "positional argument not allowed" when the I just replace mongo with mongodump 
  or
   I get </p>
  
  <blockquote>
    <p>"failed: error connecting to db: no reachable servers" when I change
    the host from
    "mongo://replset1:27017,replset2:27017,replset3:271017/test?replicaSet=replicaSetName"
    to --host replicaSetName/replset1:27017,replset:27017,replset3:27017</p>
  </blockquote>
