Any ideas?

I know the username, password, database and url are all correct

And I am fairly certain this error notice is correct, meaning that you need to check and recheck everything.

Good luck

Assuming your database is a brand new one - i.e. you don't have any useful data in it, you could do worse than simply delete the database that you can't connect to and create a brand new one using the username and password you know to be correct. Then point your new install at the new database.

This then eliminates the possibility that you mistyped a username or password when creating the database, an easy thing to do.
