Yes, they are absolute fine. Even I deleted the database twice and created 2-3 more times to see if there was some confliction around, but its fine.
Establishing a database connection and some details which are as follows
•Are you sure you have the correct username and password?
•Are you sure that you have typed the correct hostname?
•Are you sure that the database server is running?
I am sure about all 3, those information I’ve put are fine!
