how to fix: 'MongoError: authentication fail' @MongoDB Atlas

I am connecting to MongoDB Atlas and getting authentication fail error.

that is my connection string:

mongodb://user:<password>@mongo-cluster-shard-00-00-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-01-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-02-ixqtu.mongodb.net:27017/test?ssl=true&replicaSet=mongo-cluster-shard-0&authSource=admin&retryWrites=true

That is what I get:

Solution

  • You have to put your user and password in your connection uri string

     mongodb://***'your user':' here comes password '***@mongo-cluster-shard-00-00-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-01-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-02-ixqtu.mongodb.net:27017/test?ssl=true&replicaSet=mongo-cluster-shard-0&authSource=admin&retryWrites=true

    e.g

     mongodb://dbuser:dbpassword@mongo-cluster-shard-00-00-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-01-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-02-ixqtu.mongodb.net:27017/test?ssl=true&replicaSet=mongo-cluster-shard-0&authSource=admin&retryWrites=true
