连接重置由对等上游问题

我已经在我的nginx服务器上安装了OSticket应用程序。

网页只是第一次打开,如果我只是刷新页面,它connection reset by peer upstream错误给connection reset by peer upstream

我尝试更改fastcgi_read_timeoutmax_execution时间,如https://laracasts.com/discuss/channels/forge/502-bad-gateway-with-large-file-uploads和https://www.scalescale.com/tips中所述/ nginx / configure-max_execution_time-in-php-fpm-using-nginx /# ,这没有帮助。

nginx错误日志:

 2017/08/07 22:15:08 [error] 26877#26877: *42 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 10.231.1.79, server: web.com, request: "GET /ticket/logo.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm/php-fpm.sock:", host: "web.com", referrer: "https://web.com/ticket/"
