Errno 10061 : No connection could be made because the target machine actively refused it ( client - server )

Question

I have a problem with these client and server codes, I keep getting the [Errno 10061] No connection could be made because the target machine actively refused it

Answer 1

Hint: actively refused sounds like somewhat deeper technical trouble, but...

...actually, this response (and also specifically errno:10061) is also given, if one calls the bin/mongo executable and the mongodb service is simply not running on the target machine. This even applies to local machine instances (all happening on localhost).

➪ Always rule out for this trivial possibility first, i.e. simply by using the command line client to access your db.
