How to set up connection to mongodb with VPN enabled?

Question

MongoDB

The problem is the following. I am writing a telegram bot. On Linux, I use windscribe as a VPN so that the bot can connect to the telegram server. The problem is that after turning on the VPN with the windscribe connect command, the connection to the database is interrupted by an error

UnhandledPromiseRejectionWarning: MongoNetworkError: failed to connect to server [localhost:27017] on first connect [MongoNetworkError: connection 0 to localhost:27017 timed out]

In this case, all work with the database looks like this:

mongoose.connect("mongodb://localhost:27017/cuba", {useNewUrlParser: true});
    const Place = mongoose.model("Place", placesScheme);
    var iataCode = '';
    await Place.findOne({name: place_name}, 'iataCode', function (err, doc) {
        iataCode = doc.iataCode;
    });
    return iataCode;

When the VPN is turned off, the connection to the database works :)

Answer 1

The answer is simple - turn off the windscribe firewall

Answer 2

Use 127.0.0.1 instead of localhost
