Laravel 502 Bad Gateway Error

Question

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 [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$

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

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

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?

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.

The php-fpm.log shows:

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

This is the output of the nginx config:

server {
    listen 80;
    listen 443 ssl;
    server_name loc.medifaktor;

Answer 1

Change your fastcgi_pass to 127.0.0.1:9000 in your website's nginx sites_enabled conf file.

Answer 2

If you recently ran sudo apt-get update and installed a new version of PHP, and use nginx, make sure you've updated your fastcgi_pass setting in /etc/nginx/sites-enabled, e.g.:

fastcgi_pass unix:/run/php/php7.3-fpm.sock;

You should also make sure you install the latest version of the pdo_pgsql extension.
