We got this issue in production while running normally (without) production.

/build/cpprest-2i1wUL/cpprest-2.10.2/Release/src/websockets/client/ws_client_wspp.cpp:315: web::websockets::client::details::wspp_callback_client::connect_impl()::<lambda(websocketpp::connection_hdl)> [with WebsocketConfigType = websocketpp::config::asio_tls_client; websocketpp::connection_hdl = std::weak_ptr<void>]: Assertionm_state != CLOSED' failed.`

Any suggestions on how to fix this ?

This is the method we use to close socket

int Suki_ASR_Nvoq::Disconnect(void)
{
    try
    {
        printf("Closing websocket connection \n");fflush(stdout);
        nvoq_streamer.close().then([](){  std::cout << " Successfully closed websocket connection. \n"; });
    }
    catch(const websocket_exception& e)
    {
        std::cout << " Warning Failed while closing web socket"<< e.what() << "\n";
        return -1;
    }
    return 0;
}

Any Exception we can add to catch the error here so that we can void programing ending abruptly because of segfault ?
