Der DNS-Abfragename existiert nicht ⇐ Python

[Anonymous]

Ich verbinde mich zum ersten Mal mit Python unter Ubuntu 22.04 mit der Atlas-Mongodb. Ich erhalte jedoch die folgende Fehlermeldung bezüglich DNS.
Ich habe einige ähnliche Threads gesehen, konnte mein Problem jedoch nicht lösen. Könnten Sie mir bitte helfen?
from pymongo import MongoClient
import dns.resolver

def get_database():
#Provide the mongodb atlas url to connect python to mongodb using pymongo
CONNECTION_STRING = “mongodb+srv://projegui:@clusterak.mongodb.net/myFirstDatabase”

#Create a connection using MongoClient. You can import MongoClient or use pymongo.MongoClient
client = MongoClient(CONNECTION_STRING)

#Create the database for our example (we will use the same database throughout the tutorial
return client[‘myFirstDatabase’]

#This is added so that many files can reuse the function get_database()
if name == “main”:
#Get the database
dbname = get_database()
