When I commented the code that does remote requests then everything's fine, otherwise error log contains an errors like: upstream prematurely closed connection while reading response header from upstream, client: 127.0.0.1, server: unga.loc, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "unga.loc", referrer: "http://unga.loc/content/test-project-4" For solving this problem I've tried to use UNIX socket and TCP connection - no result. So, I've think that is an error. Used software: nginx 1.8.0 (also tested on 1.6.3) php-fpm 5.6.9 (works fine on 5.6.7) Test script: --------------- // Execution of this (and similar) code will ends by 502 error. $ch = curl_init('https://php.net'); curl_setopt_array($ch, [ CURLOPT_HTTPGET => true, CURLOPT_RETURNTRANSFER => true, ]); $response = curl_exec($ch); curl_close($ch); var_dump($response); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69777&edit=1
