nginx 배포시 오류발생

[minwoo1999]

location /api/ {
proxy_pass http://localhost:8000;
proxy_redirect default;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}

header 및 proxy pass 설정해줘야 가능함.
