Hi there,

Luigi server is running on a remote server `my.org` at port 8082. http://my.org is publicly visible so I need to set up nginx `proxy_pass` at the remote server for being able to see the Luigi visualizer on the internet which is available at http://localhost:8082 locally.

For this purpose, I edited the last few lines-- `server{}` block of the default `/etc/nginx.conf`:

```
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

include /usr/share/nginx/modules/*.conf;

events {
worker_connections 1024;
}

http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

access_log /var/log/nginx/access.log main;

sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;

include /etc/nginx/mime.types;
default_type application/octet-stream;

include /etc/nginx/conf.d/*.conf;

server {
location / {
proxy_pass http://localhost:8082/static/visualiser/;
}
}

}
```

Then, when I plug in http://my.org/index.html on the internet, I get:

```html
<html>
<head><title>502 Bad Gateway</title></head>
<body>
<center><h1>502 Bad Gateway</h1></center>
<hr><center>nginx/1.16.1</center>
</body>
</html>
```

Can anyone please help with setting proxy_pass right?

Best,

Tashrif

Hello again,

My problem went away magically. While I have not been able to figure the reason behind the error, I think the following may have fixed it:

location / {
proxy_pass http://localhost:8082;
}

```
nginx -s stop
service nginx restart
nginx -s reload
setsebool -P httpd_can_network_connect 1
```
