I'm working on a Git server behind Nginx using the git git-http-backend script.

Currently I have a passenger server that's working serving a rails app at port 2222. However, behind the /git/ folder I want to serve git repositories. The thing is, Nginx doesn't seem to start the script. Whether I use a socket file or a different localhost post, I get a 502 error. This is showing in the Nginx Error Log:

2017/06/07 18:43:03 [error] 2147#0: *3 no live upstreams while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET /git/me/repo HTTP/1.1", upstream: "fastcgi://localhost", host: "localhost:2222"

It seems nginx is not starting the process to handle the git files.

This is my location part of the nginx setup:

location ~ /git(/.*) {
include fastcgi.conf;
include fastcgi_params;
#fastcgi_pass 127.0.0.1:8888;
fastcgi_param SCRIPT_FILENAME /Library/Developer/CommandLineTools/usr/libexec/git-core/git-http-backend;
# export all repositories under GIT_PROJECT_ROOT
fastcgi_param GIT_HTTP_EXPORT_ALL "";
fastcgi_param GIT_PROJECT_ROOT /Users/userx/Documents/Projecten/repositories;
fastcgi_param PATH_INFO $1;


fastcgi_keep_conn on;
fastcgi_connect_timeout 20s;
fastcgi_send_timeout 60s;
fastcgi_read_timeout 60s;
#fastcgi_pass 127.0.0.1:9001;
fastcgi_param REMOTE_USER $remote_user;
#fastcgi_pass unix:/var/run/fcgi/fcgiwrap.socket;
fastcgi_pass localhost:9001;

}

I can't figure it out alone, can anybody share their thoughts on this?
