What potential issue is the user facing with the code for checking server status?

The potential issue the user is facing with the code for checking server status is that the function `checkServerStatus` is calling `file_get_contents` on an HTTP URL without handling potential errors or exceptions that may occur. To solve this issue, the user should add error handling to catch any exceptions that may be thrown during the HTTP request. 

function checkServerStatus($url) {
    try {
        $response = file_get_contents($url);
        if ($response === false) {
            return "Server is down";
        } else {
            return "Server is up";
        }
    } catch (Exception $e) {
        return "Error: " . $e->getMessage();
    }
}

// Example usage
$url = "http://example.com";
echo checkServerStatus($url);
