I have an app, created in meteor.js but it shouldn't be important i think. I have also mongo cluster on mongo atlas. So far during development i connected to db by connection string without problem from my local machine. However when i created linux machine on DigitalOcean and tried to connect my app using same connection string mongodb+srv://<user>:<password>#xyz.mongodb.net/<dbName>?retryWrites=true&w=majority
I got the following error.
MongoNetworkError: failed to connect to server [xyz.mongodb.net:27017] on first connect [MongoNetworkError: connection 5 to xyz.mongodb.net:27017 closed

Do you have any idea of what could be wrong with me server config? I guess it is server config as on other machine same connection string works.
I'm working on a web application with node.js and using Mongodb for database. everything is cool when I run my app in localhost. but when I run it in a shared host it gives an error which looks like its Mongoose connection problem.
here is my code:
const uri = 'mongodb://****:****#iranroboticacademy-bdziw.mongodb.net/test';
mongoose.connect(uri,{ useNewUrlParser: true });
mongoose.connection.once('open', function(){
console.log('DataBase is connected. ');
}).on('error', function(error){
console.log('Connection error:', error);
});
and here is the erro that I get when I run the app in host:
Connection error: { MongoNetworkError: failed to connect to server [iranroboticacademy-shard-00-00-bdziw.mongodb.net:27017] on first connect [MongoNetworkError: connect ECONNREFUSED 3.226.212.92:27017]

Sure you can use the free tier of MongoDB Cloud.
It’s actually much easier to mantain than the hosted version as you have visually all under control, automatic backups etc.

I have asked my host provider in a ticket and they said it doesn’t support mongodb. I have written everything with mongodb database in my application and I really can’t change it into other things. I need to use it in this host. Is there anyone who has a solution for this?!

I have a database setup on Mlab and I have aconnection string that does work remotely. If I run my node app on docker using my local mongo, everything works as expected, however if I change the configuration and connect to my Mlab mongo, I get the following error:

Apart from handling the error on Node side (which I'm not catching, but that's another problem), how can I connect to an external mongo server form my Docker container?
I've seen this and follow the steps described there but it didn't help me.
Any suggestions?
EDIT
This is a Node app. In my Dockerfile I have the following setting:
ENV DB_HOST=mongodb+srv://<user>:<password>#<mlab>/<db_name>?retryWrites=true
And in my Node app where I have setup the database I have this:
mongoose.connect(process.env.DB_HOST, {useNewUrlParser: true, useFindAndModify: false, useCreateIndex: true});
When I print the above env variable at run time, I get the correct string for the db (running locally everything works fine).
I don't understand why the error shows localhost. This is my first time using Docker. Do I need any additional configuration so my container can talk to an external service?
I have created a Lambda Function which intends to connect to MongoDB running on EC2.
I have followed some tutorials and guaranteed that:
Lambda and EC2 run in the same VPC
Lambda has configured EC2's subnet
Lambda has its own security group my-lambda-sg
Lambda's security group is allowed in EC2's security group inbounds rules for MongoDB's port as a "Custom TCP Rule"
Lambda's role has assigned permission AWSLambdaVPCAccessExecutionRole
However, I am stil unable to connect from the lambda to the MongoDB in EC2. When I run a Test in the Lambda I get:

From API Gateway I get
You do not have permission to perform this action
And from the browser I get:
{"message": "Endpoint request timed out"}
Other Lambda's not accessing EC2 are working fine.
Any idea what could I be missing?
I found the answer. All requisites above are ok. I just needed to use the internal IP of the EC2 instead the external one in the MongoDB URL connection, to be considered a call within the VPC, as I found here AWS Lambda unable to access EC2 port within the same VPC
I need to know about the Mongo DB Remote Server Connection using in Meteor.As i did something shown below :
database = new MongoInternals.RemoteCollectionDriver("mongodb://x.x.x.x:3001/dbname");
I got the below error :
