I can't link my database

[N0V3L0S]

The truth is I don’t know what’s happening now, I’ve previously managed to connect my page to the database, but now it won’t let me, I’ve already tried changing some things in the account and so on, but I can’t connect, I get the following error, no I know if it works for you, but even so I made sure I had the name of the database and those details right, but it still fails
