Problem with setup of subdomains in flask

Hi I am trying to setup flask blueprints with subdomains. However it doesnt work. i have setup my domain to point to the digitalocean dns servers. I made a created an A record, with @ so i assume that it should cover everything behind the .mydomain.org?

my sample testfile is init.py

from flask import Flask, Blueprint
app = Flask(__name__)
app.config['SERVER_NAME'] = 'mydomain.org'


test = Blueprint('test', __name__)
@test.route("/test")
def testindex():
    return "This is test index page."

app.register_blueprint(test, subdomain='sub')

as described here https://exploreflask.com/blueprints.html

however the result is always ERR_NAME_NOT_RESOLVED.

Anybody have an idea of what im doing wrong? Thanks Best Bjoern

ERR_NAME_NOT_RESOLVED means the domain name you typed in your address bar couldn’t be resolved to an IP address. Without knowing the domain name, there’s very little that can be done to help.
