A 400 Bad Request in Django when starting out is often due to ALLOWED_HOSTS
being set to an empty list.
Set it as:
ALLOWED_HOSTS = ['*']
In its default configuration Django doesn’t log details of the problem in this
case. Would recommend adding to Django settings module:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'handlers': {
'console': {
'class': 'logging.StreamHandler',
},
},
'loggers': {
'django': {
'handlers': ['console'],
'level': os.getenv('DJANGO_LOG_LEVEL', 'INFO'),
},
},
}
This will cause Django to log details of problems it captures to the console so
they appear in the Apache error log. If you add this first and try again you
hopefully will see a message about ALLOWED_HOSTS being the issue and can thus
confirm that as the problem.
