Unable to complete Provide Database Name page

I keep getting error message: The provided database host, username, and/or password is invalid, and a connection to the database could not be established. Please enter a valid host, username and password

In the four boxes I have inserted:
Box 1: suitecrm
box 2: my host name gator****.hostgator.com
Box 3: my login Box 4: my password

What am I doing wrong?

I don’t know your setup, have you tried the host name as just localhost maybe?
