Successful payment but order was not saved in Magento 2 due to Timeout communicating with Laybuy.

[LiamKarlMitchell]

No order created in Magento 2 but payment made on Laybuys end.
You have no try catches or handling of errors!

So when there is a REST API timeout during a checkout such as in method laybuyConfirm used in execute method the inside code of your condition is not executed as everything bombs out, yet the payment was successfully captured on Laybuys end.

The default timeout for Zend Http Client is 10 seconds.
https://framework.zend.com/manual/1.12/en/zend.http.client.html

Maybe this could also be set higher as a work-around?
I'm not sure what caused it to not complete in that time but it happened.

Possible work-around, but really should have error handling.
Laybuy\Gateway\Http|\RestClient.php set a timeout.

    /**
     * Gets the HTTP client object.
     *
     * @return \Zend_Http_Client
     */
    final public static function getHttpClient()
    {
        if (!self::$_httpClient instanceof \Zend_Http_Client) {
            self::$_httpClient = new \Zend_Http_Client();
            self::$_httpClient->setConfig([
                'timeout' => 60
            ]);
        }

        return self::$_httpClient;
    }

Log lines.
