CLIENT_CONNECTION_ERROR: tls: error:00000001:lib(0):func(0):reason(1)

[sci-ripper]

Hi, I'm trying to connect to IBM Watson Text to Speech API's Websocket using libwebsockets. I based my code on a simple websocket client found on iamscottmoyers / simple-libwebsockets-example / client.c. I added support for SSL but I'm getting the following TLS error:

My code is as follows:

    {

        callback_example,
        0,

    { NULL, NULL, 0, 0 } /* terminator */
};

int main( int argc, char *argv[] )
{
    struct lws_context_creation_info info;
    memset( &info, 0, sizeof(info) );

    info.port = CONTEXT_PORT_NO_LISTEN;
    info.protocols = protocols;
    info.options = LWS_SERVER_OPTION_DO_SSL_GLOBAL_INIT;
    info.gid = -1;
    info.uid = -1;

    struct lws_context *context = lws_create_context( &info );

    time_t old = 0;
    while( 1 )
    {
        struct timeval tv;
        gettimeofday( &tv, NULL );

        /* Connect if we are not connected to the server. */
        if( !web_socket && tv.tv_sec != old )
        {
            struct lws_client_connect_info ccinfo = {0};
            ccinfo.context = context;
            ccinfo.port = 443;
            ccinfo.address = "api.eu-gb.text-to-speech.watson.cloud.ibm.com";

            ccinfo.protocol = protocols[0].name;
            ccinfo.ssl_connection   = LCCSCF_USE_SSL | LCCSCF_PIPELINE;
            web_socket = lws_client_connect_via_info(&ccinfo);
        }

        if( tv.tv_sec != old )

            lws_callback_on_writable( web_socket );

        lws_service( context, /* timeout_ms = */ 250 );
    }

    lws_context_destroy( context );

    return 0;
}

Thanks in advance!
