  1. Any update, feel free to raie a new question

  2. Try

    telnet 8080

    Could be a proxy issue … also try to launch WSUS console and connect to confirm whether WSUS is working fine.

        1. Verify Required ports based on configurations. (Ex: 80,8530 or 443 or 8531
        2. Run the tracert command to microsoft.com from wsus server like
