CURL: A TLS packet with unexpected length was received.

[Nrgyzer via Digitalmars-d]

Hi everyone,
I'm trying to retrieve some data from a url using curl. I'm using 
the following code here:

void main()
{
         ubyte[] data;

         CURL* curl = curl_easy_init();
         curl_easy_setopt(curl, CurlOption.url, "<Private HTTPS 
Url>".toStringz);
         curl_easy_setopt(curl, CurlOption.writefunction, 
&callback);
         curl_easy_setopt(curl, CURLOPT_WRITEDATA, &data);
         curl_easy_setopt(curl, CurlOption.ssl_verifyhost, false);
         curl_easy_setopt(curl, CurlOption.ssl_verifypeer, false);
         curl_easy_setopt(curl, CurlOption.verbose, 1);

	curl_easy_perform(curl);

         curl_easy_cleanup(curl);
}

But it's not working. I'm always getting the following error:

* About to connect() to <Private HTTPS Url> 443 (#0)
*   Trying <IP Address>...
* Connected to <Private HTTPS Url> (<IP Address>) port 443 (#0)
* found 160 certificates in /etc/ssl/certs/ca-certificates.crt
* gnutls_handshake() failed: A TLS packet with unexpected length 
was received.
* Closing connection 0

When using the get()-function provided by std.net.curl:

void main()
{
         get("<Private HTTPS Url>");
         // OR:
         HTTP h = HTTP("<Private HTTPS Url>");
         h.verifyHost = false;
         h.verifyPeer = false;
         h.verbose = true;
         h.perform();

}

I'm getting a similar error:

* About to connect() to <Private HTTPS Url> port 443 (#0)
*   Trying <IP Address>...
* Connected to <Private HTTPS Url> (<IP Address>) port 443 (#0)
* found 160 certificates in /etc/ssl/certs/ca-certificates.crt
* gnutls_handshake() failed: A TLS packet with unexpected length 
was received.
* Closing connection 0

I want skip the ssl-validation but it seems that curl is always 
trying to verify the ssl certificate, although I think I've 
disabled it by setting ssl_verifyhost and ssl_verifypeer to 
false/0. I can use other ssl urls without any problems...
I'm using the latest gdc arm compiler with dmd 2.066.1

I hope anyone know what I'm doing wrong here :)
