Answer 1

Can be n things, I’ve had problems with SMTP connection for a while, does the following:

1- Change the value of Smtpdebug to 1 or 2 p/ see if the connection tells you exactly where the error is, reading the error stack is critical and sometimes saves us a lot of time;

2- check if EMAIL_HOST is correct, if you are using gmail stmp is this -> smtp.gmail.com, if it is not, check the correct address according to the email you are using, on port 587

3- Still speaking in gmail, if using of course, enables the option "Access to less secure app"

Another thing I noticed is that you are not passing $mail->Smtpsecure, it is important to enable TLS encryption

$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;  

Answer 2

This means that the email server parameters (Config::EMAIL_HOST and the like) do not point to a functional SMTP server. The problem does not seem to be in the code posted.
