400 bad request - No required SSL certificate was sent

Hi,

I have the following issue - when making a Request out of the database which connects to a server which requires a certificate Oracle for whatever reason does not send it - the https-connection obviously works but I just get the response below:

<html>
<head><title>400 No required SSL certificate was sent</title></head>
<body>
<center><h1>400 Bad Request</h1></center>
<center>No required SSL
certificate was sent</center>
<hr><center>nginx</center>
</body>
</html>

I have all the necessary trusted_certs , the private key and the user_cert stored in a wallet.

Any ideas why the certificate will not be sent ?
