ServerSelectionTimeoutError when saving documents with MongoClient using VPN, Authentication error without

I was able to save information in my MongoDB database. But now I have a pymongo.errors.ServerSelectionTimeoutError. Indeed with this code:
>>> db_url = "mongodb+srv://USER:PASSWORD#cluster0.n2hnd.mongodb.net/ifresearch?retryWrites=true&w=majority"
>>> client = pymongo.MongoClient(db_url)
>>> db = client.ifresearch
>>> collection = db.sephora
>>> collection.insert_one({'artist':'lasKetchup'})
I have:

Connecting to Google Cloud SQL Server from App Engine in the same project - Login timeout

I am using the sample code that google has provided on github:
https://github.com/GoogleCloudPlatform/python-docs-samples/tree/master/cloud-sql/sql-server/sqlalchemy
I have created a Cloud SQL server on the project and when I run the main.py file from my local machine, the database gets updated OK.
However, when I deploy the same code on Google App Engine, I get the following timeout error:

You need to configure your App Engine Flex service to connect to a Cloud SQL instance.
In your app.yaml you need to set:
beta_settings:
cloud_sql_instances: INSTANCE_CONNECTION_NAME=tcp:PORT
Where the INSTANCE_CONNECTION_NAME has the following structure: <project-name>:<region-name>:<instance-name>
And when you connect, you should connect to 172.17.0.1:PORT where PORT is the port you specified in the app.yaml file

Connecting Flask To AWS RDS using Flask-SQLAlchemy

I have been trying to connect my aws RDS database instance to a flask application I have downloaded. I have been following https://medium.com/#rodkey/deploying-a-flask-application-on-aws-a72daba6bb80 and using the flask app on this github to connect to the database https://github.com/inkjet/flask-aws-tutorial. I have set the permissions on my RDS server correctly and have been using the following code to connect to the DB.
# edit the URI below to add your RDS password and your AWS URL
# The other elements are the same as used in the tutorial
# format: (user):(password)#(db_identifier).amazonaws.com:3306/(db_name)
SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://{userName}:{password}#{endpoint}:3306/{dbName}'
# Uncomment the line below if you want to work with a local DB
#SQLALCHEMY_DATABASE_URI = 'sqlite:///test.db'
SQLALCHEMY_POOL_RECYCLE = 3600
WTF_CSRF_ENABLED = True
I am still receiving a timeout error:

Based on the comments, the issue was that RDS's public accessibility setting was not enabled.
The solution was to enable it.

PyMongo Mongodb SSL Error or bad Authentification

I'm trying to use a mongo database I created but get an error I can't get rid of.
This is my code:
If I just print collection it works fine
from pymongo import MongoClient
import ssl
client = MongoClient("mongodb+srv://HugoAdmin:<XXXXXXXXXXX>#personalsite-3gjka.mongodb.net/test?retryWrites=true&w=majority")
db = client.test
db = client['Site']
collection = db['BlogPosts']
print(collection)
post = {"_id": 0, "author": "Hugo Joncour", "date": "25/03/2020"}
#collection.insert_one(post)
I get:
➜ webportfolio git:(master) ✗ Python3.6 mongo.py
Collection(Database(MongoClient(host=['personalsite-shard-00-01-3gjka.mongodb.net:27017', 'personalsite-shard-00-00-3gjka.mongodb.net:27017', 'personalsite-shard-00-02-3gjka.mongodb.net:27017'], document_class=dict, tz_aware=False, connect=True, retrywrites=True, w='majority', authsource='admin', replicaset='PersonalSite-shard-0', ssl=True), 'Site'), 'BlogPosts')
but if I want to insert post:
from pymongo import MongoClient
import ssl
client = MongoClient("mongodb+srv://HugoAdmin:<yvctrd6F7GUYBVYT>#personalsite-3gjka.mongodb.net/test?retryWrites=true&w=majority")
db = client.test
db = client['Site']
collection = db['BlogPosts']

Any idea on how to solve this ?

pymongo.errors.ServerSelectionTimeoutError

What could possibly be the reason of this error? I am using a ubuntu guest server in a windows 10 host system
The entire error is as follows:

`
train_data.py is as follows, if that helps:
features: Tuple[List[str], List[str], List[str], List[bool], List[str]] = \
extract_features.separation_of_features(parsed_json)
update_database.insert_features(features)

seems like your application is not being able to connect to database, verify if the database is actually running on localhost:27017 and accepting connections
ps: try connecting with mongoshell
