SMTP Connect() Failed: Troubleshooting Connection Timeouts

When attempting to send emails using SMTP, you may encounter the error: "SMTP -> ERROR: Failed to connect to server: Connection timed out (110)... Message was not sent. Mailer error: SMTP Connect() failed." This issue often indicates a problem establishing a connection to the SMTP server.

Potential Causes:

• Incorrect SMTP settings (e.g., hostname, port, authentication details)
• Firewall or network configuration blocking the connection
• Temporary server issues on the SMTP server side

Solution:

Review the SMTP settings specified in your code (e.g., Host, Port, Username, and Password) to ensure they match the requirements of the SMTP server you are using.

Additionally, comment out or remove the line $mail->IsSMTP(); as it is not necessary when using the SMTP configuration.

<code class="php">require 'class.phpmailer.php';
require 'class.smtp.php';

$mail = new PHPMailer();

$mail->SMTPDebug = 2; // Enable debugging
$mail->Mailer = "smtp";
$mail->Host = "ssl://smtp.gmail.com";
$mail->Port = 587;
$mail->SMTPAuth = true;
$mail->Username = "[email protected]";
$mail->Password = "mypasswword";
$mail->Priority = 1;

$mail->AddAddress("[email protected]", "Name");
$mail->SetFrom($visitor_email, $name);
$mail->AddReplyTo($visitor_email, $name);

$mail->Subject = "Message from Contact form";
$mail->Body = $user_message;
$mail->WordWrap = 50;

if (!$mail->Send()) {
    echo 'Message was not sent.';
    echo 'Mailer error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent.';
}</code>

If the problem persists, check your firewall or network settings to ensure that the SMTP port (typically 587 or 465) is not being blocked. You can also try using a different SMTP server to rule out server-side issues.
