“I used VPN to connect, but after connecting to the proxy server, I disconnected without shaking hands. Have you encountered any similar situations?”?? Request help. Thank you very much, everyone.

I use the HTTPS long connection mode and use data streams for transmission, so I can see the HTTP connection process. I saw that he disconnected me after connecting to the proxy server and preparing to shake hands. I don’t know whether the proxy server disconnected me or the GPT server disconnected me? I hope I can seek help. Thank you very much
