    Ensure that your app has the necessary network permissions. Add the following permission to your AndroidManifest.xml file within the <manifest> tag:

    <uses-permission android:name="android.permission.INTERNET" />

    Also verfify the Cross-Origin Resource Sharing (CORS) policy on your Django server.

    Install the library

    python -m pip install django-cors-headers

    and then add it to your installed apps:

    INSTALLED_APPS = (
    ...
    'corsheaders',
    ...
)

    You will also need to add a middleware class to listen in on responses:

    MIDDLEWARE = [
    ...,
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    ...,
]

    and specify domains for CORS, e.g.:

    CORS_ALLOWED_ORIGINS = [
    'http://localhost:3030',
]

    Refer the following answer for configuring CORS in django.
