Django + MongoDB - pymongo.errors.ServerSelectionTimeoutError

Question

Im trying to implement MongoDB in my Django app like this:

DATABASES = {   
    'default': {      
        'ENGINE': 'djongo',      
        'NAME': 'mongodb',  
        }
    }

But I get this error:

pymongo.errors.ServerSelectionTimeoutError: localhost:27017: [WinError 10061]

No connection could be made because the target machine actively refused it

Traceback:

Thank you very much for any help

I have intermittent ServerSelectionTimeoutError's when using djongo under heavy load over gunicorn/gevent. Seems to happen more as I get more traffic. Not sure if its something to do with the timeout settings. — radtek

Check first that you passed through all these steps Try changing port of mongodb , that will make it work hopefully :)

   1) pip install djongo
   2) DATABASES = {
            'default': {
                    'ENGINE': 'djongo',
                    'NAME': 'your-db-name',
            }
    }

    3) python manage.py makemigrations
    4) python manage.py migrate
