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 am connecting a Nodejs app running on the GCP Kubernetes cluster. Before, it worked fine, when I enabled VPC Peering and I was using the connection string (Private). It is recommended on the Atlas dashboard:
mongodb+srv://(username):(password)#<cluster_name>-pri.m6tkv.gcp.mongodb.net/<database_name>?retryWrites=true&w=majority
I followed this tutorial to setup: https://docs.atlas.mongodb.com/security-vpc-peering/
I cannot understand since my app has been running for quite a while with this configuration. But one fine day, the app running on a pod in my GCP cluster is unable to connect.
Thats the error message:
Connected mongodb failed MongoNetworkError: failed to connect to server [<cluster_name>-00-00-pri.m6tkv.gcp.mongodb.net:27017] on first connect [MongoNetworkError: connection timed out

I switched back to the old connection (Standard), my app works again. The connection string:
mongodb+srv://(username):(password)#<cluster_name>.m6tkv.gcp.mongodb.net/<database_name>?retryWrites=true&w=majority
So connection via VPC Peering is having some problem, I couldn't find any clue.
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 a Meteor Application. I am trying to deploy my application by the custom deployment procedure (on my local machine) by following this article:
https://guide.meteor.com/deployment.html#custom-deployment
But I am facing this error when I run the application via node:

Steps I performed:
First I came into the Meteor App directory and ran:
meteor build ../myapp-build --architecture os.linux.x86_64
Then I provided me the myapp.tar.gz and I extracted that.
Than I did:
- cd programs/server && npm install
- export MONGO_URL='mongodb://martini-henry:123456#192.168.100.2:9001/myappdb'
- export ROOT_URL='http://192.168.100.2:9000'
And at last when I ran:
- cd ../.. node main.js
I got that error above. What could be wrong here? Can anyone help me what I am doing wrong here?
