Trying to run truffle console I got this typical error:

enter image description here

I've checked my configuration and it seems OK to me (I don't know why truffle is trying to connect to 127.0.0.1). Here you can see my project:

As you can see, the deployment of my 5 contracts was good. Infura is also working because I'm receiving data and I'm able to see my contracts deployed on https://kovan.etherscan.io. Moreover, Metamask is also connected and working:

Connected sites

Account 1 is connected to these sites. They can view your account address.

infura.io

Am I forgetting something?

Reset to default

If you don't specify the network in truffle it will default to the network named development. if you don't define the development network in your config file it will default to the default development network spec it has hardcoded.

to use your kovan network you will need to specify the network :

truffle console --network=kovan

this will work with any truffle command (compile, migrate, etc.)

  • Maybe a silly question, but... how can i see my dapp on my browser? I mean: i have all of that but now...? Because I tried localhost with the port but I think I'm doing something in a wrong way.

  • @Joncarre - try localhost:3000 - I'm guessing you are using truffle that ships with create-react-app so starting the frontend client will be a different command yarn start

  • @HAS-Jack in my app.js I have my web3.providers.httpprovider('http://localhost:7545') but I'm trying to access to it via browser and nothing happen (Unable to connect error). By the way, do I need node running? Sorry but I'm still trying to understand all the components here. Because I thought that part is executed in Kovan (or I'm wrong?) Moreover, I'm trying to access via https://kovan.infura.io/v3/API_KEY cause I'm using Infura

    @Joncarre by default don't think truffle creates a dapp for you, so you will have to do it yourself or use an existing truffle box boilerplate project, there the docs will guide you.
