+# Proxy Server Setup for Production
+
+## Problem
+The proxy server isn't working because `VITE_PROXY_SERVER` is being set to `http://localhost:8090` during the Docker build, which won't work from the browser on a remote server.
+
+## Solution
+
+When building and deploying on the remote server, you need to build the Docker image with the correct build argument.
+
+### For Manual Docker Run Commands
+
+Rebuild the Jumble image with the correct proxy URL:
+
+```bash
+docker build \
+  --build-arg VITE_PROXY_SERVER=http://jumble.imwald.eu:8090 \
+  -t silberengel/imwald-jumble:12 \
+  .
+
+# Then push to Docker Hub
+docker push silberengel/imwald-jumble:12
+```
+
+**Note on Docker Network:**
+
+You only need to create the network once (it persists). Check if it exists first:
+
+```bash
+# Check if network exists
+docker network ls | grep jumble-network
+
+# If it doesn't exist, create it (only needed once)
+docker network create jumble-network
+```
+
+### For Docker Compose
+
+### 1. Set Environment Variables Before Building
+
+```bash
+export JUMBLE_PROXY_SERVER_URL="http://jumble.imwald.eu:8090"
+export JUMBLE_SOCIAL_URL="http://jumble.imwald.eu:32768"
+```
+
+### 2. Rebuild the Docker Image
+
+```bash
+docker-compose build --no-cache
+```
+
+### 3. Restart the Containers
+
+```bash
+docker-compose down
+docker-compose up -d
+```
+
+## How to Check if it's Working
+
+1. After deploying, open the browser console on `https://jumble.imwald.eu`
+2. Navigate to a page with a URL that should show OpenGraph data
+3. Look for `[WebService]` log messages that will show:
+   - Whether the proxy server is configured
+   - What URL is being used to fetch metadata
+   - Any errors (CORS, network, etc.)
+
+## Important Notes
+
+- The `VITE_PROXY_SERVER` value is baked into the JavaScript bundle during build time
+- You MUST rebuild the Docker image if you change `JUMBLE_PROXY_SERVER_URL`
+- The proxy server's `ALLOW_ORIGIN` must match the frontend URL (`JUMBLE_SOCIAL_URL`)
+- Both must use the same protocol (http vs https)
+
+## Troubleshooting
+
+If you see errors in the console:
+- `[WebService] No proxy server configured` - `VITE_PROXY_SERVER` is undefined or empty
+- `[WebService] CORS/Network error` - The proxy URL might be wrong, or CORS isn't configured
+- `[WebService] Failed to fetch metadata` - The proxy server might not be running or accessible
