Twitter Oauth doesn't work when trying to login

[arfathyahiya]

Hi, I was trying Twitter Quickstart from the flask-dance documentation and for some reason it isn't working

Here's my code

twitter_blueprint = make_twitter_blueprint(api_key=app.config.get("twitter_api_key"),
                                           api_secret=app.config.get("twitter_api_secret"))
app.register_blueprint(twitter_blueprint, url_prefix='/login')

@app.route('/')
def twitter_login():
    print("Incoming Request")
    print(dir(twitter))
    if not twitter.authorized:
        print("Redirecting")
        return redirect(url_for('twitter.login'))
    print("Getting Account Info")
    account_info = twitter.get('account/settings.json')

    if account_info.ok:
        account_info = account_info.json()
        return f"<h1>Your twitter name is {account_info['screen_name']}</h1>"

when redirecting using return redirect(url_for('twitter.login')) i get the following error OAuth 1 request token error: Token request failed with code 403, response was '<?xml version='1.0' encoding='UTF-8'?><errors><error code="415">Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings</error></errors>'. I even set the callback url in twitter developer portal just as mentioned http://localhost:5000/login/twitter/authorized

EDIT: it was something wrong with localhost twitter asks to mention 127.0.0.1
