Hello,
I’m encountering an issue while trying to launch my Flask server, specifically with the connection to MongoDB. I’m receiving the following error message:

I have tried connecting to MongoDB using MongoDB Compass, and it works perfectly fine. However, when I launch the Flask server, I encounter this error. Here’s how I am starting the server:
from api_folder.controller.main import app
if __name__ == "__main__":
app.run(debug=True, host='0.0.0.0', port=8080)
I would appreciate any assistance or insights into resolving this issue. Thank you in advance for your help!
[EDIT]
pymongo version: 4.3.3
pymongo.MongoClient(“mongodb+srv://user:password@cluster0.qqawu.mongodb.net/myFirstDatabase?retryWrites=true&w=majority”)
