오늘 아침 7시 20분 경 기존 사용중이던 EN 노드에서 블록 동기화가 중단되었습니다  
(특별한 로그는 없었습니다)

이후 부트노드를 찾지 못해서 계속 블록 동기화가 안되고 있습니다  
혹시 몰라서 /var/kend/data 를 삭제 후 fast sync 데이터로 교체하였으나  
계속 동일한 증상을 겪고 있습니다  
verbosity 를 5로 변경하여 로그를 찍어보니 아래 로그가 계속 반복되고 있습니다

사용하시는 네트워크가 Baobab/Cypress 중 어떤 것인지 알 수 있을까요?

방화벽 등에서 32323, 32324 포트를 막거나 하는 변경은 없으셨던거죠?

저희쪽에서 이슈가 재현되지 않아 당장 원인을 파악하는데는 시간이 조금 걸릴거 같네요.  
우선은 직면한 이슈를 해결하기 위해 아래 명령어를 통해 static 하게 PN과 연결하는 방안을 권장드립니다.

```auto
// statically connect to a PN
admin.addPeer("kni://772b3b5ed369641d5812ff0872785e2decd9161cf168855c16805b87bfc4bca7872f597dc1ca7c17f69dcbe6aaa84e48353e9c1a48b60af5440606298df5fdf9@52.79.95.186:32323?ntype=pn")

// statically connect to another PN 
admin.addPeer("kni://81c44374fe0ff0ab1193b05bea30ffcb36bd976cf4e251b209ccf198e1436c90894f4e8e69d62de8fa6fe89e6ccf7defd51b74e13f2d628a086b6e3adcc8ffb0@13.209.215.234:32323?ntype=pn")

네 방화벽 등 설정은 변경하지 않았습니다  
addPeer 이후에는 잘 syncing 하고 있네요
