Laravel 502 Bad Gateway错误

我将Laravel 5.3与最新的Homestead安装程序一起使用.当我向我的API发出POST请求时，根据日志文件出现此错误:

I use Laravel 5.3 with the latest Homestead Setup. When I make a POST Request to my API, I get this error according to the log file:

2016/10/29 12:44:34 [错误] 776#0:* 28 recv()失败(104:连接 从对等方重置)，同时从上游客户端读取响应标头: 192.168.10.1，服务器:loc.medifaktor，请求:"POST/api/v1/mfusers HTTP/1.1"，上游:"fastcgi://unix:/var/run/php5-fpm.sock$

2016/10/29 12:44:34 [error] 776#0: *28 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 192.168.10.1, server: loc.medifaktor, request: "POST /api/v1/mfusers HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock$

我使用POSTMAN发出POST请求，将其发送到URL: http://loc.medifaktor/api/v1/mfusers

I use POSTMAN to make the POST Request sending it to the URL: http://loc.medifaktor/api/v1/mfusers

这是一个家用安装，并且在我的计算机上本地运行.

which is a homestead installation and runs locally on my computer.

此错误中提到的客户端地址是192.168.10.1，这实际上是不正确的，因为我使用的是192.168.10.10.这可能是错误，我该如何解决?

The client address mentioned in this error is 192.168.10.1 which is actually not true, as I use 192.168.10.10. Could this be the mistake and how do I change that?

我使用的是Laravel的全新安装，我尝试了其他类似GET的请求，这些请求都可以正常工作.只是POST请求会引发此错误.

I am using a fresh install of Laravel and I tried other requests like GET which work fine. Just the POST Request throws this error.

php-fpm.log显示:

The php-fpm.log shows:

[29-Oct-2016 13:47:15] NOTICE: configuration file /etc/php5/fpm/php-fpm.conf test is successful

这是nginx配置的输出:

This is the output of the nginx config:
