[bjornstromberg]

see https://github.com/oatpp/oatpp-websocket/issues/38#issuecomment-1173165297 it seems to be the same issue.

well it seems its more of a bad description of what should happen.

client connects to third party api online.

expected a client / server local ping pong

Hello @bjornstromberg ,

It looks that API key for demo server is expired. I've updated the API key in the example and it works:

  auto connection = connector->connect("v3/channel_1?api_key=VCXCEuvhGcBDP7XhiJJUDvR1e1D3eiVjgZ9VRiaV&notify_self");

The 'client' example can be modified to connect to localhost with the 'server' example with

int local = 1;
  std::string url = "localhost";
  uint16_t port = 8000;
  std::string conn_str = "ws";
  if (!local)
  {
    url = "demo.piesocket.com";
    port = 80;
    conn_str = "v3/channel_1?api_key=oCdCMcMPQpbvNjUIzqtvF1d2X2okWpDQj4AwARJuAgtjhzKxVEjQU6IdCjwm&notify_self";
  }

  auto connectionProvider = oatpp::network::tcp::client::ConnectionProvider::createShared({url, port});

  auto connector = oatpp::websocket::Connector::createShared(connectionProvider);

  auto connection = connector->connect(conn_str);

and the examples can be easily build by modifying the main CMake file in /src to have at the end
