Grav: Cannot get grav to work on a nginx reverse proxy

[i5o]

Hello.

We are trying to set up a grav instance on our server using nginx 1.15.5 as a reverse proxy for an httpd 2.4.6 server. But it's not working, we can't register an admin.

_s1: is our nginx server
s4b: is our httpd server (which includes grav files)_

_the instance is supposed to be behind https://url.com/grav_

this is our nginx config on s1:

location /grav {
  rewrite  ^/grav/(.*) /$1 break;
  proxy_pass http://s4b;
  proxy_set_header Host server.com;
  proxy_set_header X-Real-IP $remote_addr;
}

this our httpd config on s4b:

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot /var/www/csites/server.com/public
    ServerName server.com
    ServerAlias server.com

    ErrorLog logs/grav.error
    CustomLog logs/grav.access combined
    <IfModule mod_deflate.c>
       SetOutputFilter DEFLATE
       AddOutputFilterByType DEFLATE text/plain text/html text/xml
       Header append Vary User-Agent env=!dont-vary
    </IfModule>
</VirtualHost>

then, on system/config/system.yaml we changed the following values:

custom_base_url: /grav
reverse_proxy_setup: true

then we go to url.com/grav, we get the admin prompt and once clicking submit I get this

Oops there was a problem, please check your input and submit the form again.

I did google already, and tried few things, but nothing worked.
Except commenting the code that returns that error, but once I did that

1. I was able to register an admin
2. I wasn't able to login due to "Invalid Security Token", I also did follow the instructions but nothing worked.

FWIW, this did not happen when pointing a grav instance only to a domain.com. it only seems to be a problem when trying to use a "subfolder".

Thanks :)

Did you use the example webserver-configs/nginx.conf that's included with Grav as a basis for your configuration???

Hey @rhukster , thanks for replying.

The nginx conf won't work for us since this is a grav instance running on a apache instance, so we just use proxypass

any other ideas?

Either you're skim these configs with your ass or you incompitent dummy that just unable to see difference between fastcgi and proxy_pass.
Make your choice.

Anyway this bug still persist and i get mumbling like this:

PHP webserver requires a router to run Grav, please use:
php -S exs-elm.ru:80 system/router.php
