# 🔒 HTTPS/SSL Setup Complete! ✅

## 🎉 Your Site is Now Secure

**Access your site with HTTPS:**

- ✅ **<https://houseofprayer.ddns.net>** (Secure!)
- ✅ HTTP automatically redirects to HTTPS

---

## ✅ What Was Fixed

### 1. SSL Certificate Installed

- **Provider:** Let's Encrypt (Free, Auto-Renews)
- **Certificate Location:** `/etc/letsencrypt/live/houseofprayer.ddns.net/`
- **Expiration:** March 16, 2026 (Auto-renewal enabled)
- **Auto-Renewal:** Certbot scheduled task runs twice daily

### 2. API Configuration Fixed for Other Devices

**Problem:** Settings page was hardcoded to use `port 8080`, causing "Offline" errors on other devices

**Solution:** Updated [frontend/src/api.js](frontend/src/api.js) to:

- ✅ Auto-detect protocol (http/https) from current page
- ✅ Remove port number when accessing via DNS hostname
- ✅ Keep port 8080 only for localhost development
- ✅ Nginx reverse proxy handles all routing

### 3. How It Works Now

**Localhost (Development):**

```javascript
// When accessing http://localhost:5100
API URL: http://localhost:8080/api
Settings: { protocol: "http", hostname: "localhost", port: "8080" }
```

**DNS Hostname (Production):**

```javascript
// When accessing https://houseofprayer.ddns.net
API URL: https://houseofprayer.ddns.net/api
Settings: { protocol: "https", hostname: "houseofprayer.ddns.net", port: "" }
```

**Result:** Other devices connect to your DNS hostname without port numbers!

## 📱 How Other Devices Connect Now

### Before (Broken)

❌ Devices tried: `http://houseofprayer.ddns.net:8080/api`

- Port 8080 not forwarded on router
- Devices showed "Offline"

### After (Fixed)

✅ Devices use: `https://houseofprayer.ddns.net/api`

- Nginx on port 443 (HTTPS) handles requests
- Port 443 forwarded on router → Works everywhere!

---

## 🧪 Verified Tests

```bash
# ✅ HTTPS Homepage
curl -I https://houseofprayer.ddns.net
# Result: HTTP/2 200 OK

# ✅ HTTPS API
curl -s https://houseofprayer.ddns.net/api/health
# Result: {"status":"ok","ts":"2025-12-16T03:58:13.530451"}

# ✅ HTTP Auto-Redirects to HTTPS
curl -I http://houseofprayer.ddns.net
# Result: HTTP/1.1 301 Moved Permanently → HTTPS
```

---

## 🔧 Nginx Configuration

Certbot automatically updated `/etc/nginx/sites-enabled/church-music`:

```nginx
server {
    server_name houseofprayer.ddns.net;
    
    # Frontend
    location / {
        proxy_pass http://127.0.0.1:5100;
    }
    
    # Backend API
    location /api/ {
        proxy_pass http://127.0.0.1:8080/api/;
    }

    listen 443 ssl; # HTTPS
    ssl_certificate /etc/letsencrypt/live/houseofprayer.ddns.net/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/houseofprayer.ddns.net/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
}

server {
    # Redirect HTTP → HTTPS
    if ($host = houseofprayer.ddns.net) {
        return 301 https://$host$request_uri;
    }
    
    listen 80;
    server_name houseofprayer.ddns.net;
    return 404;
}
```

## 🌐 Router Port Forwarding Required

**⚠️ CRITICAL:** Forward these ports on your router:

| External Port | Internal IP | Internal Port | Protocol |
|---------------|-------------|---------------|----------|
| 80 (HTTP) | 192.168.10.130 | 80 | TCP |
| 443 (HTTPS) | 192.168.10.130 | 443 | TCP |

**Why Port 443?**

- HTTPS uses port 443 (not 8080!)
- Nginx listens on 443 and proxies to backend port 8080
- Devices connect to HTTPS without specifying port

---

## 📱 Testing on Other Devices

### 1. **From Your Local Network:**

```
Open browser on phone/tablet:
https://houseofprayer.ddns.net
```

### 2. **From Outside Network (Internet):**

```
Requires port forwarding setup first!
https://houseofprayer.ddns.net
```

### 3. **Check Settings Page:**

```
https://houseofprayer.ddns.net
→ Click "Settings" icon
→ Should show:
   Protocol: https
   Hostname: houseofprayer.ddns.net
   Port: (empty)
   Status: ✅ Connected
```

## 🔒 SSL Certificate Auto-Renewal

Certbot automatically renews certificates:

```bash
# Check renewal status
sudo certbot renew --dry-run

# View renewal timer
sudo systemctl status certbot.timer

# Manual renewal (if needed)
sudo certbot renew
```

**Certificate expires:** March 16, 2026  
**Auto-renewal:** Runs twice daily  
**You don't need to do anything!** 🎉

3. Acts like a native app!

**HTTPS required for PWA features** ✅ Done!

---

## 🔍 Troubleshooting

### "Site Can't Be Reached" from Outside Network

- Check router port forwarding (ports 80 & 443)
- Verify DNS points to your current public IP
- Test: `curl -I https://houseofprayer.ddns.net` from server

### Settings Show "Offline"

1. Open browser DevTools (F12)
2. Go to Application → Storage → Local Storage
3. Delete `api_settings` entry
4. Refresh page
5. Should auto-detect HTTPS DNS hostname

### SSL Certificate Warnings

- Ensure DNS hostname matches certificate
- Check certificate not expired: `sudo certbot certificates`
- Verify firewall allows port 443

### Backend API Not Working

```bash
# Test backend directly
curl http://localhost:8080/api/health

# Test via Nginx
curl https://localhost/api/health

# Check service status
sudo systemctl status church-music-backend
```
