PHPMailer all of the sudden not working

So I have this application that I built that uses PHPMailer to send mail. The code works perfectly from my local machine, and it was working perfectly on the server up until yesterday. However now when I run the code on my server I get:

Message could not be sent.Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

I have literally tried everything. I cannot figure out why this is not working. From the server as the user the site is installed to, I can telnet localhost 465 and I can telnet localhost 587 so the server is up, and its not blocking connections to itself.

The only thing I can think of is, this being a Cpanel server some sort of update must have happened with apache/PHP which caused something to not work right with this. I know the problem is not with the mail server and its not with the code (since it works when I run this exact code from my local machine) which only leaves out the PHP/Apache config on the server...

Does anyone have any insight on what this might be?

PS- I have to use SSL, its the only thing my server supports that I'm aware of,at least I've never had any luck using TLS or unencrypted.

Here is my code:

require("vendor/autoload.php");
$mail = new \PHPMailer;
// set up mail settings
$mail->isSMTP();
$mail->Host = 'my.host.com';
$mail->SMTPAuth = true;
$mail->Username = 'username';
$mail->Password = 'password';
$mail->SMTPSecure = 'ssl';
$mail->Port = 465;

$mail->Debugoutput = function($str, $level) {
    $GLOBALS['debug'][] = $Host . " - " . $str . " - " . $level;
};

$mail->SMTPDebug = 2;
$mail->CharSet = "UTF-8";
$mail->setFrom(.....);
$mail->addAddress(.....);
$mail->isHTML(true);
$mail->Subject = 'Here is the subject';
$mail->Body    = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional //EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html><body>This is the HTML message body <b>in bold!</b></body></html>';

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

EDIT:

I changed debug level to 3 (for connection debugging, derp) and I get this:

[0]=> string(88) " - Connection: opening to ssl://host.host.com:465, timeout=300, options=array ( ) - 3"

[1]=> string(291) " - Connection failed. Error #2: stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed [/path/to/vendor/phpmailer/phpmailer/class.smtp.php line 294] - 3"

[2]=> string(175) " - Connection failed. Error #2: stream_socket_client(): Failed to enable crypto [/path/to/vendor/phpmailer/phpmailer/class.smtp.php line 294] - 3"

[3]=> string(215) " - Connection failed. Error #2: stream_socket_client(): unable to connect to ssl://my.host.com:465 (Unknown error) [/path/to/vendor/phpmailer/phpmailer/class.smtp.php line 294] - 3"

[4]=> string(52) " - SMTP ERROR: Failed to connect to server: (0) - 1"

[5]=> string(89) " - SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting - 3" }

So I was right, its SSL related... So anyone know how to fix this?

The exact same thing happened with one of our live sites a while back. Spent a few hours troubleshooting the code (we're using PHPMailer as well), but it ended up being a firewall update on the data center. Check your cPanel settings and/or open a ticket with your hosting provider.

If you didn't change anything on your code and it suddenly stopped working, it's most likely NOT an issue with your code. In my case it was the server firewall blocking outbound connections. Look into that.
