Laravel mail change from name

I have problem with send mail massage (Laravel 5.5). This is my code but doesn't work, no errors. But if I delete line: ->from('test2@test.com','Test Name'), it's work. Do you have any idea how i can resolve this problem?

public function build()
    {
        return $this->from('test2@test.com','Test Name')
            ->subject('Subject')
            ->view('accountoffice::emails.send_pit_email')->with([
            'pit4_amount' => 10,
            'pit5_amount' => 20,
            'pit8_amount' => 30,
            'client' => $this->client,
        ]);
    }
