+# 🛠️ How to Create a Free Discord Proxy
+
+Hugging Face officially blocks outgoing connections to Discord's IP addresses on Free Tier Spaces to prevent spam. While our built-in DNS script cleanly bypasses blocks for Telegram and WhatsApp, Discord is blocked at the physical IP firewall level.
+
+This means the native n8n "Discord" node will always hang and fail with a "Connection closed unexpectedly" error.
+
+To work around this, you can easily create your own private Discord proxy using Cloudflare Workers. It takes about 2 minutes and is 100% free (allowing up to 100,000 requests per day).
+
+## Step-by-Step Guide
+
+### Step 1: Create a Cloudflare Worker
+1. Log into [Cloudflare](https://dash.cloudflare.com/) (create an account if you don't have one).
+2. On the left sidebar, go to **Workers & Pages**.
+3. Click **Create Worker** -> **Start with Hello World!**.
+4. Name it something memorable, like `discord-proxy`, and click **Deploy**.
+
+### Step 2: Add the Proxy Code
+1. Once deployed, click the **Edit Code** button.
+2. In the online code editor, delete the existing code and replace it entirely with this 6-line snippet:
+
+```javascript
+export default {
+  async fetch(request) {
+    const url = new URL(request.url);
+    url.hostname = 'discord.com';
+    return fetch(new Request(url, request));
+  }
+}
+```
+
+3. Click **Save and Deploy** in the top right corner. Cloudflare will generate a unique URL for you (e.g., `https://discord-proxy.yourname.workers.dev`).
+
+### Step 3: Use the Proxy in n8n
+Because the native Discord Node hardcodes connections to `discord.com` when using Bot tokens, you must use the **Webhook** method.
+
+1. Add the standard **Discord** node to your n8n workflow.
+2. Under "Authentication", select **Webhook**.
+3. Take your normal Discord Webhook URL and replace `discord.com` with your new worker domain.
+   * *Original:* `https://discord.com/api/webhooks/123456/abcdef`
+   * *New:* `https://discord-proxy.yourname.workers.dev/api/webhooks/123456/abcdef`
+4. Create a new Discord Webhook Credential in n8n and paste that **New URL** into the "Webhook URL" field.
+5. Setup your message (e.g., set the text to "Hello World") and click **Execute Node**. Your message will instantly appear in Discord!
+

+*Note: If you ever upgrade your Hugging Face Space to a paid hardware tier, the outgoing firewall restriction is removed, and you can go back to using the native n8n Discord node directly!*
