why windows use postman can't connect vmware fedora ws server

[RageCPP]

I create a simple ws server with follow code

#include "uWebSockets/App.h"

int main() {
  uWS::App()
      .connect("/",
               [](auto* res, auto* req) {
                 // When a client connects to the HTTP proxy server. It should
                 // answer 200 OK.
                 res->writeStatus("200 OK")->end();
               })
      .get("/*", [](auto* res, auto* req) { res->end("Hello World!"); })
      .listen("0.0.0.0", 9001,
              [](auto* token) {
                if (token) {
                  std::cout << "Listening on port " << 9001 << std::endl;
                }
              })
      .run();

  std::cout
      << "Shoot! We failed to listen and the App fell through, exiting now!"
      << std::endl;
}

then I use curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: <websocket-server-hostname>" http://0.0.0.0:9001,I get good res

HTTP/1.1 200 OK
