DB connection error: "Access denied for user..."

Having difficulty establishing my DB connection. I had been having issues so I deleted the entire project, database, and user(s) and started completely over. I’m now getting the following error:

Error using this Database Connection!
Server Response: SQLSTATE[28000] [1045] Access denied for user ‘robDB’@‘ip-***-*--***.ip.secureserver.net’ (using password: YES)

My FTP target is working fine. I know my credentials are correct. Is this something that can be solved with the host?

Thanks.
