deploy Django2 on heroku , but can not open the webpage in browsers - django

Question

I did a django project on python, and push it to heroku, but when I try to access it with
https://desolate-oasis-71960.herokuapp.com
browser can not load it.
I use django2.1.3 on python3, here is my settings.py:
import os
import django_heroku
# Build paths inside the project like this:os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
--snip-
# Activate Django-Heroku.
django_heroku.settings(locals())
#setting Heroku
cwd = os.getcwd()
if cwd == '/app' or cwd[:4] == '/tmp':
import dj_database_url
DATABASES= {
'default': dj_database_url.config(default='postgres://localhost')
}
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO','https')
#ALLOWED_HOSTS = ['*']
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATIC_URL = '/static/'
STATICFILES_DIRS = (
os.path.join(BASE_DIR,'static'),
)
but after I push the project to heroku ,I can not open the webpage, then I run the command: heroku logs, here is the log :
2018-11-16T03:47:55.000000+00:00 app[api]: Build succeeded
2018-11-16T03:48:48.803513+00:00 heroku[router]: at=error code=H14

fwd="202.119.45.10" dyno= connect= service=status=503
bytes=protocol=https
and I also try to load it locally with command
heroku local
the command window always shows like this:

and I need to push "control"+"C" to exit
Help me please

Answer 1

In settings.py:
ALLOWED_HOSTS = ['desolate-oasis-71960.herokuapp.com']

Answer 2

Thanks, I have solved this by re-building Procfile by using command in terminator:
touch .Procfile
and I delete my .git file(have to delete this file),
then re-initialize .git file by command
git init
and it worked.
