Uncaught PDOException: Could not connect to database how to fix?

Question

PHP

I was given a project. I'm trying to open it myself and I'm facing a problem (screenshot).


In Google they write that the problem is with the drivers, but they are connected.



To work with the database, the project uses RedBean

. I've already tried a bunch of everything, but no movements at all. Maybe somewhere you need to specify some other port or something like that. I'm running the project through OpenServer. With all this, the project is 100% working. because the person who threw it to me all worked. The problem is somewhere on my side.
