Hi all!
I know this issue has been created in several other post but I am not sure the fix is the same…
So in fact I have set those 2 settings:
rest\_listen\_uri = [http://192.168.1.10:9000/api/](http://192.168.1.10:9000/api/)
web\_listen\_uri = [http://192.168.1.10:8000/](http://192.168.1.10:8000/)
I need the rest api to be on a specific IP because I use the filebeat sidecar
I also set the web interface to an ip ans a port to reach it instead of using a tunnel.
My issue is when I use nginx to access the web interface. This is what I have from the doc:
> server
> {
> listen 80 default\_server;
> listen [::]:80 default\_server ipv6only=on;
> server\_name 192.168.1.10;
>
> ```
> location / {
> proxy_set_header Host $http_host;
> proxy_set_header X-Forwarded-Host $host;
> proxy_set_header X-Forwarded-Server $host;
> proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
> proxy_set_header X-Graylog-Server-URL http://$server_name/api;
> proxy_pass http://192.168.1.10:8000;
> }
>
> ```
>
> }
With this setting, I got the issue of 404 - cannot POST.
Any advice on this?
Note that I am using graylog server 2.4.6 and sidecar 0.1.6 installed onto another host.
**Update**
I have tested with:
web\_listen\_uri = [http://127.0.0.1:8000/](http://127.0.0.1:8000/)
and
proxy\_pass [http://127.0.0.1:8000](http://127.0.0.1:8000)
and got the same issue…
**Possible FIX**
This nginx config seems to work!! (ref: [API browser (Swagger interface) does not work with AWS appliance · Issue #3519 · Graylog2/graylog2-server · GitHub](https://github.com/Graylog2/graylog2-server/issues/3519#issuecomment-336631052))

What Version of Graylog did you use?
Did you checked running API and Web on the same port?
Check that part of the configuration: [http://docs.graylog.org/en/2.4/pages/configuration/web\_interface.html#making-the-web-interface-work-with-load-balancers-proxies](http://docs.graylog.org/en/2.4/pages/configuration/web_interface.html#making-the-web-interface-work-with-load-balancers-proxies)
check the settings that are assumed in the examples and adjust that to your configuration - or change the configuration to the examples.
