Error while opening the deployed Django project to Railway

Question

I am getting this error while opening the deployed site on railway .

I looked for the solution and found that we need to change the host of mysql settings, so I changed them. These are my new database settings.

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'my_db',
        'USER': 'root',
        'PASSWORD': 'toor',
        'HOST': '0.0.0.0',
        'PORT': '3306',
        'OPTIONS': {
            'init_command': "SET sql_mode='STRICT_TRANS_TABLES'"
        }
    }
}

I am still getting the error. What should I do?
