The account malicar, which obviously belongs to you, has been archived since 2018. I can unarchive it if you want, but you'll have to delete your new account. The new account malicard was created today. I can enable remote postgresql on the new account, but I find it odd that your database doesn't match the username on your account. Furthermore, cpanel shows your database user as existing, but on the command line the user doesn't exist. All these oddities are probably related to you having more than one account in the system.
