Error while connecting to localhost

[zivlakmilos]

After I update my operating system and MongoDB I am started to get error while trying to connect to local MongoDB server.

MongooseServerSelectionError: connect ECONNREFUSED ::1:27017 at NativeConnection.Connection.openUri (.../node_modules/mongoose/lib/connection.js:797:32) at .../node_modules/mongoose/lib/index.js:332:10 at .../node_modules/mongoose/lib/helpers/promiseOrCallback.js:32:5 at new Promise (<anonymous>) at promiseOrCallback (.../node_modules/mongoose/lib/helpers/promiseOrCallback.js:31:10) at Mongoose._promiseOrCallback (.../node_modules/mongoose/lib/index.js:1158:10) at Mongoose.connect (.../node_modules/mongoose/lib/index.js:331:20) at Object.<anonymous> (.../app.js:45:10) at Module._compile (node:internal/modules/cjs/loader:1097:14) at Object.Module._extensions..js (node:internal/modules/cjs/loader:1149:10) { reason: TopologyDescription { type: 'Unknown', servers: Map(1) { 'localhost:27017' => [ServerDescription] }, stale: false, compatible: true, heartbeatFrequencyMS: 10000, localThresholdMS: 15, logicalSessionTimeoutMinutes: undefined } }

This is URL that I am using to connect to db: mongodb://localhost:27017/dbname

Also, when I try same URL in MongoDB Compass, everything works without problem.

I found out that when I change localhost to 17.0.0.1 it works perfect. I am note sure what causing this, but localhost should be same as 127.0.0.1. I tough fist that is problem with MongoDB server listening, but if that's case, it wouldn't be working from Compass too.

Versions:

• Node: v17.1.0
• MongoDB: 5.0.4
• Mongoose: 6.1.0

Start your MongoDB server with ipv6 support, or take a look at your /etc/hosts file and look for a line that looks like ::1 localhost. Make sure that ::1 localhost is after 127.0.0.1 localhost. The ::1:27017 part of your stack trace makes it look like localhost is getting resolved to an ipv6 address.
