How to add a server to the nginx configuration of a yunohost server?

[Red]

My YunoHost server

Hardware: Old laptop or computer
YunoHost version: 4.0.8.2
I have access to my server : Through SSH + SFTP | through the webadmin | direct access via keyboard / screen
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : that’s a bit the point of my question

Description of my issue

Hey, i installed yunohost on a debian 10.6 computer. I also installed a radarr server, and i’m wondering how to edit NGINX’s files to allow me to access the server ?
when just adding theses lines :

                location /radarr/ {
                    proxy_pass http:// 127.0.0.1:7878;
                }

to the /etc/nginx/conf.d/domain-name.conf file it redirects to the yunohost SSO, but doesn’t let me access the server. How can i add an external server ?
thanks !

Hello
I think you could use the redirect app to get it works
