I working on Building a shopping cart Using Node.js Express and mongodb, using this tutorial, and so far there is no problem, but now when i run the server, it shows '
Server running on port 3000
' But the problem is when I connect to localhost:3000 it shows,
This page isn’t working localhost didn’t send any data. ERR_EMPTY_RESPONSE
I check some error logs but didn't work. DB connection is also working, and DB has fetching data
There is no error shown in the terminal, How to solve this
