Heroku: This site can’t be reached

问题

My heroku app cannot be accessed after a build. The logs show that the web server node and worker node both are listening. It's a flask app run by gunicorn and it has 2 addons - newrelic and redistogo.

Error:

This site can’t be reached.
appname.herokuapp.com’s server IP address could not be found.
DNS_PROBE_FINISHED_NXDOMAIN

EDIT:

Procfile:

web: newrelic-admin run-program gunicorn app:server
worker: python worker.py

Worker:

import os

import redis
from rq import Worker, Queue, Connection

listen = ['high', 'default', 'low']

redis_url = os.getenv('REDISTOGO_URL', 'redis://localhost:6379')

conn = redis.from_url(redis_url)

if __name__ == '__main__':
    with Connection(conn):
        worker = Worker(list(map(Queue, listen)))
        worker.work()

回答1:

The app is accessible now. It seems to be downtime with Heroku. Although they haven't reported this in their status page.
