Hey dude!

It's probably just that your 'Redirect URI(s)' (in the steemconnect dashboard app settings) is different than the 'redirect_uri'(in config.js), they need to be exactly the same including slashes.

• Create the App through steemconnect

• My Apps > App name > Edit (top right)

• Add http://localhost:3000/auth/ for working locally
  

• Click Save

• Rename config.example.js to config.js

• edit config.js

• client_id is the name of your app in steemconnect

• redirect_uri matches what was used on steemconnect dashboard
  

• You don't need to use the Client Secret anywhere (that's basically your password for that app account)

• Session Secret needs to be a random string, longer the better e.g
  

Looks like everything is running okay, I'd just double check the redirect_uri match in your code + steemconnect dashboard.

let me know if you get it working or have any other issues. :)
