I'm currently working through the following tutorial to learn to work with Azure's cosmosdb via the mongodb API: https://docs.microsoft.com/en-us/azure/cosmos-db/tutorial-develop-mongodb-react
The finished repo for this tutorial is here: https://github.com/Azure-Samples/react-cosmosdb but so far I'm just on part 5 where you actually try to connect to the cosmos database.
I ran into an issue with the mongoose version and substituted the repo code with this found here: Error connecting to Azure: Illegal character in password with mongoose 5.0.1 but works in 4.13.9
I also downgraded my required mongodb version to 2.2.33 as it seems that the newer version of mongo doesn't work. (See the comments at the bottom of: https://docs.microsoft.com/en-us/azure/cosmos-db/mongodb-mongoose)
These two seemed to solve some of my errors, however I'm stuck on how to solve the following:
{ MongoError: failed to connect to server [react-cosmos-db-tori.documents.azure.com:10255] on first connect [MongoError: connection 0 to react-cosmos-db-tori.documents.azure.com:10255 timed out]

As far as I can tell this is just a timeout because it can't connect to my database.
Here's my code:
const mongoose = require('mongoose');
const env = require('./env/environment');
mongoose.Promise = global.Promise;
function connect() {
return(
mongoose.connect('mongodb://react-cosmos-db-tori.documents.azure.com:10255/react-cosmos-db-tori?ssl=true', {
auth: {
user: 'react-cosmos-db-tori',
password: '<mypasswordhere>'
}
})
.then(() => console.log('connection successful'))
.catch((err) => console.log(err))
)
}
module.exports = {
connect,
mongoose
};
Heres a screenshot of my connection string page in Azure:
and here's my package.json:
{
"name": "express-react-starter",
"version": "0.1.0",
"private": true,
"dependencies": {
"body-parser": "^1.17.2",
"cookie-parser": "^1.4.3",

"mongoose": "^5.0.7",
"morgan": "^1.8.2",

},
"devDependencies": {
"concurrently": "^3.5.0",
"nodemon": "^1.12.0",
"react-scripts": "1.0.10"
},
"scripts": {

"build": "react-scripts build && mv build server",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
},
"proxy": "http://localhost:3001"
}
I also get the following error on start:
DeprecationWarning: `open()` is deprecated in mongoose >= 4.11.0, use `openUri()` instead, or set the `useMongoClient` option if using `connect()` or `createConnection()`. See http://mongoosejs.com/docs/connections.html#use-mongo-client
When I try to refresh the page that I'm expecting to see an empty array, I only see a chrome error: localhost didn’t send any data. ERR_EMPTY_RESPONSE and the following is displayed in the console: GET /api/heroes - - ms - - and I don't get the big MongoError above. But I also don't get my 'connection successful' either.
I was thinking that it might perhaps be an issue with what I put as the databasename in the connect url, so I created a collection called heroes_test and tried using mongodb://react-cosmos-db-tori.documents.azure.com:10255/heroes_test?ssl=true but the same thing happens.
Anyone know what's going on here? Am I maybe using the promise thing wrong? Any help would be appreciated!
