Installation on NAS

I am trying to install on NAS. I am at the database config file, but I keep getting “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” error

What am I doing wrong? I thought SuiteCRM will create a database?

If you are using MySQL then SuiteCRM will try to create a database. The username and password you provided, must have the security rights to create a database. If you are connecting to MSSQL database, You must first create the database.

It might be faster to create the database first and then configure SuiteCRM to use that database.
