Hello,
I do not speak German, so I used google to translate the pages as I filled out the form. After submitting the error, it took a good amount of time to return anything to my browser. Maybe 35 seconds. Within the page, I receive this error:
--
Die folgenden Fehler traten während der Registrierung auf
Ihre E-Mail-Adresse oder Ihr E-Mail-Anbieter wurde gesperrt. Bitte geben Sie eine andere E-Mail-Adresse an. Wenn Sie möchten, können Sie sich an den Administrator wenden.
Die grafische Sicherheitsüberprüfung konnte wegen Serverproblemen nicht durchgeführt werden. Bitte versuchen Sie es später noch einmal.

Translated through the browser, I see:
--
The following error occurred during the registration
Your e-mail address or your e-mail provider is not available. Please enter a different email address. If you want, you can contact the administrator .
The graphical security clearance because of server problems could not be performed. Please try again later.

I would assume the translation was not perfect, but it sounds like there are 2 errors. One saying I have a bad email. Since I used my real gmail account, I do not see why that would be an issue. And then a second error about "graphical security".
Since I am not familiar with your signup program, I can not quote you on the specific ways to address this. If this was me, I would make a test page outside your signup form to test the reCAPTCHA functionality alone. I see with their PHP example (
https://developers.google.com/recaptcha/docs/php) that there is a check to see if the response is valid, and there is also an error message:
if (!$resp->is_valid) {
die ("The reCAPTCHA wasn't entered correctly. Go back and try it again. (reCAPTCHA said: " . $resp->error;
}
I would try to capture the specific error being returned.
If you have already tried this, I do not have any other recommendations. Maybe someone else here has gone through this. But to me, when it takes that long form a form to submit and return, something within my coding is not able to resolve until it times out. In your case, the communication with the server may be timing out because your server blocks outgoing calls, or maybe you IP has been blocked by reCAPTCHA. Either way.. capturing the compete response / flow, as well as reviewing your server logs (which may require you to enable displaying errors) may help.
