1. vps로 서버이전 중입니다.

2. 도메인 땡겨오느라 불안정한 상황입니다.

어제까지만 해도 불안정하긴 했으나 구서버나, 신서버나 접속이 되긴 됐었습니다.

그런데 오늘부터 갑자기 엄청나게 딜레이 생기더니 500에러를 뱉어내네요;; (그 사이 손댄것은 없습니다.)

3. 티켓을 이용하여 apm등을 설치했는데, 보니까 아파치랑 nginx랑 두 가지가 깔려있었습니다.

우선 아파치부터 에러코드를 살펴봤는데요

라고 뜹니다. 클플 사용중이며 ssl도 아마 적용되어 있는걸로 압니다.

접속이 잘 되다가 갑자기 이러는 이유를 모르겠습니다. 

무엇을 보면 되는걸까요?
