I\'m trying to connect to my mongoDB server via the connection string given to me by mongo:
"mongodb+srv://david:p
The same problem i faced with mongoDB password authentication failed.
"Error: bad auth Authentication failed."
As per Pawan's suggestion given above i replaced my login password in MONGO_URI link with database password and it works. be sure to check that one also.
If you not generated the generate new one or if created earlier then replace with new one.
