+## Production Server Configuration (10.4.0.205)
+
+### Caddy Reverse Proxy
+- **Location:** `~/docker/caddy/config/Caddyfile`
+- **Container Name:** `caddy`
+- **Admin API:** `0.0.0.0:2019`
+
+### DeafMissoula.org Configuration
+- **Docker Container:** `deafmissoulaorg-app-1`
+- **Internal Port:** 801
+- **Docker Network:** Separate from Caddy (different network IDs)
+- **Current IP:** 172.18.0.6 (as of March 4, 2026)
+
+**Important:** Because Caddy and deafmissoula containers are on different Docker networks, the Caddyfile must use IP addresses instead of container names for routing.
+
+### Caddyfile Entry:
+```
+deafmissoula.org {
+	reverse_proxy 172.18.0.6:801
+}
+```
+
+### Common Issues & Solutions
+
+#### Issue: Website returns 502 after Docker rebuild
+**Cause:** Docker container IP address changed during rebuild
+
+**Solution:**
+1. Check current container IP:
+   ```bash
+   ssh chaulmark@10.4.0.205 "docker inspect deafmissoulaorg-app-1 --format '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}'"
+   ```
+
+2. Update Caddyfile:
+   ```bash
+   # Download Caddyfile
+   scp chaulmark@10.4.0.205:~/docker/caddy/config/Caddyfile /tmp/Caddyfile
+   
+   # Edit locally to update IP address in deafmissoula.org section
+   
+   # Upload back
+   scp /tmp/Caddyfile chaulmark@10.4.0.205:~/docker/caddy/config/Caddyfile
+   ```
+
+3. Reload Caddy:
+   ```bash
+   ssh chaulmark@10.4.0.205 "docker exec caddy caddy reload --config /etc/caddy/Caddyfile"
+   ```
+
+4. Verify:
+   ```bash
+   curl -I https://deafmissoula.org
+   ```
+
+#### Better Long-term Solution
+Connect both Caddy and deafmissoula containers to the same Docker network to use container names instead of IP addresses, which would prevent this issue.
