"mongodb+srv://:@cluster0.vvkuk.mongodb.net/" also in the atlas, in security go to network access, there will be small buttons edit and delete click on edit, and in the edit, there will to two options the first option is ADD CURRENT IP ADRESS & the second option will be ALLOW ACCESS FROM ANYWHERE go for the first option & then click confirm

const mongoAtlasUri =
  "mongodb+srv://<username>:<password>@firstcluster.4rc4s.mongodb.net/<dbname>?retryWrites=true&w=majority";

try {
  // Connect to the MongoDB cluster
  mongoose.connect(
    mongoAtlasUri,
    { useNewUrlParser: true, useUnifiedTopology: true },
    () => console.log(" Mongoose is connected"),
  );
} catch (e) {
  console.log("could not connect");
}

const dbConnection = mongoose.connection;
dbConnection.on("error", (err) => console.log(`Connection error ${err}`));
dbConnection.once("open", () => console.log("Connected to DB!"));

MongoError: authentication fails - It means your name or password or dbname is not correct -

uri sample -

const uri =
    "mongodb+srv://<username>:<password>@firstcluster.4rc4s.mongodb.net/<dbname>?retryWrites=true&w=majority";

Suppose username is - najim & password is 1234 & dbname is pets (Note - default dbname is test but you can write whatever you want) then my uri will be with above credentails -

const  mongoAtlasUri =
        "mongodb+srv://najim:[email protected]/pets?retryWrites=true&w=majority";

to connect with moongoose

try {
    // Connect to the MongoDB cluster
     mongoose.connect(
      mongoAtlasUri,
      { useNewUrlParser: true, useUnifiedTopology: true },
      () => console.log(" Mongoose is connected")
    );

  } catch (e) {
    console.log("could not connect");
  }

try {
mongoose.connect( uri, {useNewUrlParser: true, useUnifiedTopology: true}, () =>
console.log("connected"));    
}catch (error) { 
console.log("could not connect");    
}

this works fine , try it

The answer in this related post is correct. You should:

  • not mix options with connection string (if done so)
  • make sure your IP you are running on is whitelisted and your network allows connections to Atlas
  • make sure the user has sufficient permissions

  • use the connection string as is provided by atlas and just provide it to 

    mongoose.connect(uri);
