Cannot connect after installing from README

[ngbao161199]

Hi @mohitarora3 ,

I'm Bao - a student who is learning Flask in Vietnam and I've just accessed: http://localhost:5000/

I got this error after installing like instructions from README. Can you help me check this issue? Thanks a lot!

By the way, I want to ask another question.

In your file ecommerce/mongo.py, I've checked this line:

app.config['MONGO_URI'] = 'mongodb://vidulkumar:[email protected]:57493/mydatabase'

Do this cause the error that I mentioned before? Thanks for reading, @mohitarora3
