node.js code

    const express = require("express");
    var mongoose = require("mongoose");

    mongoose.connect(
    "mongodb://dfgg:cdFJFJnnsDXC@dev-docdb-cluster-1.cluster-ct090j7ac20n.us-east-1.docdb.amazonaws.com:27017/cnox?ssl=true&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false",{
            ssl: true,
            sslValidate: true,
            sslCA: `/home/ubuntu/rds-combined-ca-bundle.pem`,
        }
    );

I am using this code to connect aws documentdb from node.js application. I am getting above error.

I am able to connect to doc db from shell so there is no error with credentials I am able to connect using mongodb client so something is wrong with mongoose connection.

Please take a look
