アマゾンLinuxのAMI：nginxの上流

Question

からレスポンスヘッダを読みながらのように、私はエラーログにnginxのエラーを受け取る上流（接続がタイムアウト110）：タイムアウトこれはAWSを実行ワードプレスウェブサーバである

[error] 4257#0: *3470 upstream timed out (110: Connection timed out) while reading response header from upstream, client 120.X.X.X 

とリバースプロキシとしてnginxを使用しています。ここに私のconfファイルがあります：

クライアント側では、http 502（悪いゲートウェイ）が受信されます。何が間違っていますか？

Answer 1

nginx.confファイルで、proxy_read_timeoutの値を以前に90に設定していた300に引き上げました。nginxとphp-fpmを再起動した後、問題は解決されました。
