  Solution

       It happens when the Internet is not stable.  
      1. Check the internet condition on your workshop. 
         (1) If you connect to the internet by WiFi, go to the place where the WiFi signal is good and retry.                 If you still have the problem, check next.  

         (2) If you connect to the Internet by WiFi, connect the Internet by LAN cable and retry. 
              If you still have the problem, go to No. 2.

      2.  Connect to the Internet on another network(Internet Cafe, home, or etc.) and retry.
