I'm trying to use the Pion net library (v2.0.10) to create an SSL client to connect to our Pion HTTP service. I'm having trouble with authentication. I've pieced together a code snippet below. The connection works but I get an authentication error. I can connect with Firefox so I know the HTTP service is operating properly and the username and password I'm using are the same. Can someone point out what I'm doing wrong? Thanks!

boost::shared_ptr context(
new pion::net::TCPConnection::SSLContext(scheduler.getIOService(),
boost::asio::ssl::context::sslv23));

TCPConnectionPtr tcp_conn(
new TCPConnection(scheduler.getIOService, *context);

boost::system::error_code error_code;
error_code = tcp_conn->connect(endpoint->get_host(), endpoint->get_port());
if (error_code || !tcp_conn->is_open())
{
std::cout << "Socket connect FAILED: " << error_code << std::endl;
}
else
{
std::cout << "Socket connect succeeded: " << error_code << std::endl;
error_code = tcp_conn->handshake_client();
if (error_code)
{
std::cout << "Handshake FAILED!" << std::endl;
}
}

HTTPRequest request(endpoint->get_url());
PionUserPtr user(new PionUser(username, password));

request.setUser(user);

request.setContentType(HTTPTypes::CONTENT_TYPE_TEXT);
request.setMethod("POST");

request.setVersionMajor(1);
request.setVersionMinor(1);

request.addHeader("Host", endpoint->get_host());

request.setContentLength(input_data_size);
char* content = request.createContentBuffer();

memcpy((void*)content, (void*)input_data.get(), input_data_size);

boost::system::error_code error_code;
request.send(*tcp_conn, error_code);

if (!error_code)
{
HTTPResponse response(request);
response.receive(*tcp_conn, error_code);
....
