+Reverse proxy configuration for Radarr is done like most other applications. Below is a minimal example, in a standard Nginx install this file should be places in /etc/nginx/sites-available and then symlinked to /etc/nginx/sites-enabled.
+```
+    server
+    {
+        listen      80;
+        server_name YOUR_DOMAIN;
+    
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_redirect off;
+        proxy_set_header Host $http_host;
+    
+        location /YOUR_URL_BASE
+        {
+            proxy_pass  http://localhost:7878;
+        }
+    }
+```
+
+Here `YOUR_DOMAIN` needs to be replaced with the domain you are using to reverse proxy e.g. `radarr.example.com` or `example.com`. If you want nginx to proxy all requests to sonarr, leave out the `server_name` line and change the listen line to `listen 80 default_server`.
+
+Similarly `YOUR_URL_BASE` needs to be replaced with the URL Base set in radarr's settings. If it is empty, the line should read `location /`.
+
+After reloading nginx you should now be able to find radarr at http://YOUR_DOMAIN/YOUR_URL_BASE.
