Nginx proxy server returns 404 (Not found )

1

I have Passbolt server installed on my Virtual machine and now I am trying to set up nginx proxy on host machine in front of Passbolt.

Here is my nginx/sites-available/default file:

server {

   listen 443 ssl;


   location /passbolt {
   proxy_pass https://10.xx.xx.xx::8082;
   proxy_set_header Host $host;

   # re-write redirects to http as to https, example: /home
   proxy_redirect http:// https://;


}

}

When i tried to access 10.xx.xx.xx/passbolt in browser, NGINX returns “404 Not Found”.
Anyone has idea?

Thanks
