When I set up my MongoDB Atlas database and try to upload data to it, I get the following error: 

in _resolve_uri
raise ConfigurationError(str(exc))
pymongo.errors.ConfigurationError: The DNS response does not contain an answer to the question: _mongodb._tcp.thecluster-noqgm.gcp.mongodb.net. IN SRV

In turn, if I try to enter the MongoShell, I get the following error:

2020-03-06T16:27:23.304+0100 E QUERY [js] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: No connection could be made because the target machine actively refused it. :

It could be something with my home network, since I tried to upload data from a different network and it worked without issue.
