MySQL server has gone away - 2006 ../uploads/sermons/2019.03.08-Bro-GK.mp3
$uploadDirectory = "../uploads/sermons/";
require '../includes/config.php'; // this contains the connection ($conn)
$errors = []; // Store all foreseen and unforseen errors here
$fileExtensions = ['mp3','wav']; // Get all the file extensions
$fileName = $_FILES['file']['name'];
$fileSize = $_FILES['file']['size'];
$fileTmpName = $_FILES['file']['tmp_name'];
$fileType = $_FILES['file']['type'];
$fileExtension = explode('.',$fileName);
$fileExtension = end($fileExtension);
$fileExtension = strtolower($fileExtension);

$title = mysqli_real_escape_string($conn,$_POST["Title"]);
$speaker = mysqli_real_escape_string($conn,$_POST["Speaker"]);
$date = mysqli_real_escape_string($conn,$_POST["date"]);
$date = date('Y-m-d', strtotime($date));
$description = mysqli_real_escape_string($conn,$_POST["Description"]);
$query = "Insert into `sermons` (`Title`,`Description`,`Speaker`,`Date`,`Link`) values('$title','$description','$speaker','$date','$uploadPath');";
$result = mysqli_query($conn,$query) or die(mysqli_error($conn)." - ".mysqli_errno($conn)." ".$uploadPath);

It seems like you're running into a read timeout, because the upload takes longer than the script keeps the connection open. Try setting the value of the MYSQLI_OPT_READ_TIMEOUT to something suitable like so mysqli_options($conn, MYSQLI_OPT_READ_TIMEOUT, value_in_seconds);. You'll probably have to setup $conn before actually connecting, in case you run into this bug https://bugs.php.net/bug.php?id=76703
