In settings.py file , I only want to store media files there no static files.
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
AWS_S3_SECURE_URLS = False
AWS_QUERYSTRING_AUTH = False
AWS_S3_ACCESS_KEY_ID = '*******'
AWS_S3_SECRET_ACCESS_KEY = '******'
AWS_STORAGE_BUCKET_NAME ='shuboy.media'
AWS_S3_CUSTOM_DOMAIN = '%s.s3.amazonaws.com' % AWS_STORAGE_BUCKET_NAME
STATIC_URL = '/static/'
MEDIA_URL = 'https://%s/media/' % AWS_S3_CUSTOM_DOMAIN
STATICFILES_DIRS = [
os.path.join(BASE_DIR, "appname/static"),
]
STATIC_ROOT = os.path.join(BASE_DIR, "STATIC_CDN")
MEDIA_ROOT = '%s.s3.amazonaws.com/media/' % AWS_STORAGE_BUCKET_NAME
STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'
If anybody tell me why this error is occurring and how can I solve this issue ? Any further suggestions will be appreciable .

Answer 1

The above error is happening because your bucket name has a "." in it.
The work around for this issue is go to ~/.boto configuration file search for https_validate_certificates and set it to False it will work.
Or remove the "." from your bucket name for it to work correctly.

Answer 2

The boto package doesn't fully support S3 buckets with dots in the name, because of SSL certificate scope.
Either create and use a new bucket without a dot, like "shuboymedia", or add this monkey patch in your settings:
import ssl
if hasattr(ssl, '_create_unverified_context'):
ssl._create_default_https_context = ssl._create_unverified_context
