TemplateDoesNotExist only happen on prod ec2 but Templates works on local

Question

I have running on my windows pc a django app with following structure

this app also runs locally and works with this settings

    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'django_mysql',
    'users',
    'posts',
    'comments',
]

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',


  #  'chango2.middelware.ProfileCompletionMiddelware',
]

libraries: {
    'tags': 'tags',

}

ROOT_URLCONF = 'chango2.urls'
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR,'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',

            ],
        },
    },
]

this app work as expected when its runned locally with python manage.py runserver

now i trying to deploy this app on a ec2 , i have configurated the security gropus to allow port 80 **and **8000 for inbound and outbound

on ec2 i run with

(env) ubuntu@ip-172-31-3-242:~$ gunicorn --bind 0.0.0.0:8000 chango2.wsgi:application

app starts listening on port 8000 got the first page but for other link then i recive the the only thing changed between prod and local was ALLOWED_HOSTS = [my ec2 dns]

and DATABASES (but that its working)
