When you run Nextcloud behind a reverse proxy like Nginx Proxy Manager (NPM), Nextcloud’s logs will often show the IP address of the proxy server itself rather than the actual IP address of the end-user. This can render security features like brute-force protection and audit logging ineffective.

This guide provides two methods to configure Nginx Proxy Manager and Nextcloud to ensure the correct user IP address is always forwarded.

### **Step 1: Configure Nextcloud to Trust the Proxy**

This step is mandatory regardless of which NPM configuration method you choose below. You must tell Nextcloud to trust requests coming from your Nginx Proxy Manager instance.

1. Log in to your Nextcloud server’s command line, for example, via SSH.

2. Open your `config.php` file for editing. The path is typically `/var/www/nextcloud/config/config.php`, but it may vary depending on your installation.

3. Add the `trusted_proxies` parameter to the configuration array. Replace `192.168.1.150` with the actual IP address of your Nginx Proxy Manager server.

4. **Optional:** The original discussion mentions adding a `'forwarded_for_headers'` line. However, Nextcloud uses the standard `X-Forwarded-For` header by default, so this line is usually **not** necessary. Only add the following if you still have issues after completing the other steps:

5. Save the file and exit the editor (in `nano`, press `Ctrl+X`, then `Y`, then `Enter`).

### **Step 2: Configure Nginx Proxy Manager (Choose One Method)**

You only need to follow **one** of the two methods below to configure NPM to send the correct IP headers. Method A is generally recommended for its simplicity.

#### **Method A: Using the NPM Web Interface (Recommended)**

This method uses the advanced settings for a specific proxy host.

1. Log in to your Nginx Proxy Manager web portal.

2. Navigate to **Hosts** \> **Proxy Hosts**.

3. Find your Nextcloud host in the list and click the three-dot menu on the right, then select **Edit**.

4. In the Edit Proxy Host window, click on the **Advanced** tab.

5. In the **Custom Nginx Configuration** text box, add the following lines:

6. Click the **Save** button.

#### **Method B: Using a Custom Configuration File (Advanced)**

This method creates a global proxy configuration file that can be applied to multiple hosts.

1. Access the file system where your Nginx Proxy Manager data is stored.

2. Navigate to the Nginx configuration directory, which is typically located at `.../data/nginx/`.

3. Inside this directory, you should see a `proxy_host` folder. Go into it.

4. Look for or create a folder named `conf.d`.

5. Inside the `.../nginx/proxy_host/conf.d/` folder, create a new file named `proxy.conf`.

6. Add the following content to your new `proxy.conf` file:

7. Save the file. You may need to restart your Nginx Proxy Manager container for the change to be loaded.

### **Conclusion**

After completing Step 1 and one of the methods in Step 2, your Nginx Proxy Manager will correctly forward visitor IPs, and your Nextcloud instance will trust and log them. You can verify this by checking the `nextcloud.log` file or the “Logging” section in your Nextcloud admin settings after a failed login attempt. The IP address shown should now be the real external IP, not your proxy’s local IP.
