Nginx as reverse proxy for Ajenti

EDIT: Adding proxy_set_header Origin http://$host; fixes it for me.

After upgrading to the latest version of ajenti I also have this problem as well. Error 403 Invalid Origin. This is my setup.

server {    listen 443 ssl;    server_name ajenti.mymagicalwebsite.com;    ssl on;    if ($scheme = http) {        return 301 https://$server_name$request_uri;    }    location / {        proxy_pass  http://localhost:8000;        proxy_redirect off;        proxy_set_header        Host                $host;        proxy_set_header        X-Real-IP           $remote_addr;        proxy_set_header        X-Forwarded-For     $proxy_add_x_forwarded_for;        proxy_http_version 1.1;        proxy_set_header        Upgrade         $http_upgrade;        proxy_set_header        Connection      "upgrade";        proxy_read_timeout      36000s;  ## Timeout after 10 hours    }}

Funny that it all worked a version ago with this exact same setup.

Here's how I would do it:

Use location ~ /ajenti.* instead to match Ajenti's resources URLs.

Edit: tested that and it works.
