"Code connection" doesn't work

Code connection v 1.5 사용중이며, 계속 "서버에 연결할 수 없습니다" 오류 발생함.

어쩌다가 실행이 될 때도 있지만, 다시 하면 같은 오류 발생.

Code connection을 다시 설치해도 같은 증상.

윈도우 방화벽을 해제해도 동일함.

 

I am using code connection v 1.5. But since before, "connection closed." or "could not connect to server" Error occurs.
Sometimes it runs but eventually fails again.
I reinstalled the code connection, turned off the windows firewall but the result is the same.
Perhaps a new version of Minecraft is causing this problem.
