Тайм-аут скрипта перед возвратом заголовков: wsgi.py; Django приложение на эласте c бобовый стебель

Я развертываю приложение Django, но в последние 2 дня я случайно начал получать тайм-аут сценария перед возвратом заголовков: wsgy.py со следующими журналами: 

[Sun Feb 16 03:02:30.697009 2020] [mpm_prefork:notice] [pid 20719] AH00163: Apache/2.4.41 (Amazon) mod_wsgi/3.5 Python/3.6.8 configured -- resuming normal operations

Кажется, это быть похожим на проблему, упомянутую здесь , но эти ответы немного беспорядочные и, кроме того, не решают мою проблему. Вот некоторые дополнительные файлы:

wsgi.py: 

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'app.settings')

application = get_wsgi_application()

Все перечисленные ниже параметры - elasti c beanstalk:

01_packages.config: 

packages:
  yum:
    git: []
    postgresql93-devel: []
option_settings:
  "aws:elasticbeanstalk:application:environment":
    DJANGO_SETTINGS_MODULE: "app.settings"
    "PYTHONPATH": "/opt/python/current/app/app:$PYTHONPATH"
    "ALLOWED_HOSTS": ".elasticbeanstalk.com"
  "aws:elasticbeanstalk:container:python":
    WSGIPath: app/wsgi.py
    NumProcesses: 3
    NumThreads: 20
  "aws:elasticbeanstalk:container:python:staticfiles":
    "/static/": "www/static/"

02_ python .config (с пропущенными командами continer_com): 

option_settings:
  "aws:elasticbeanstalk:application:environment":
    DJANGO_SETTINGS_MODULE: "app.settings"
    "PYTHONPATH": "/opt/python/current/app/app:$PYTHONPATH"
    "ALLOWED_HOSTS": ".elasticbeanstalk.com"
  "aws:elasticbeanstalk:container:python":
    WSGIPath: app/wsgi.py
    NumProcesses: 3
    NumThreads: 20
  "aws:elasticbeanstalk:container:python:staticfiles":
    "/static/": "www/static/"

03_ apache .config: 

container_commands:
  01_setup_apache:
    command: "cp .ebextensions/enable_mod_deflate.conf /etc/httpd/conf.d/enable_mod_deflate.conf"
files:
  "/etc/httpd/conf.d/eb_healthcheck.conf":
    mode: "000644"
    owner: root
    group: root
    content: |
        <If "req('User-Agent') == 'ELB-HealthChecker/2.0' && %{REQUEST_URI} == '/'">
            RequestHeader set Host "app.com"
        </If>

app.config: 

option_settings:
  aws:elasticbeanstalk:container:python:
    WSGIPath: app/wsgi.py


files:
  "/etc/httpd/conf.d/wsgi_custom.conf":
    mode: "000644"
    owner: root
    group: root
    content: |
      WSGIApplicationGroup %{GLOBAL}

container_commands:
  01_migrate:
    command: "python manage.py migrate"
    leader_only: true


packages:
  yum:
    git: []
    postgresql93-devel: []

Как видите, я в основном разочаровался, пытаясь найти разные решения без каких-либо реальных решений. Я также, очевидно, не настолько знаком с Apache и elasti c бобовым стеблем и испытывал трудности. Любое руководство будет оценено.
