Error trying to connect with French bank

[MZK91]

Hi everybody and thank for your work,

I'm trying to use that class to connect to a French Bank but i'm facing that issue, that i tried to figure out for days and can't find a way to solve it.

So i've followed your examples showed in the presentation, but I keep having this response :

DER was not encoded.

Here is a sample of my code:

    $x509 = new X509Generator();
    $x509->setCertificateOptions($x509->getCertificateOptions());

    $client->setX509Generator($x509);


    try {
        $client->INI();
        /* @var \AndrewSvirin\Ebics\Services\KeyRingManager $keyRingManager */
        /* @var \AndrewSvirin\Ebics\Models\KeyRing $keyRing */
        $keyRingManager->saveKeyRing($keyRing);
    } catch (EbicsResponseExceptionInterface $exception) {
        echo sprintf(
            "INI request failed. EBICS Error code : %s\nMessage : %s\nMeaning : %s",
            $exception->getResponseCode(),
            $exception->getMessage(),
            $exception->getMeaning()
        );
    }
