Deploy Dograh AI with your own custom domain name for a professional production setup. By now, you should be able to create and test a voice agent by following the previous guide to setup the platform on a remote server using [Docker](docker#option-2%3A-remote-server-deployment)

## What is Custom Domain Deployment?

Custom domain deployment allows you to run Dograh AI with a personalized domain name (like `voice.yourcompany.com`) instead of using IP addresses. This setup includes:

- **Custom Domain**: Access your application via a memorable domain name
- **Automatic SSL**: Proper SSL certificates from Let's Encrypt or similar providers
- **Professional Setup**: Production-ready configuration for business use
- **Easy Sharing**: Share a clean URL with your team and customers

## Prerequisites

Before starting, ensure you have:

- A domain name you own (e.g., `yourcompany.com`)
- Access to your domain's DNS settings (usually through your domain registrar)
- Dograh AI already running on your server via the [remote deployment](docker#option-2%3A-remote-server-deployment) guide
- Your server's public IP address

## Step 1: Configure DNS Records

You need to create a DNS record that points your domain to your server's IP address.

### Add an A Record

Log in to your domain registrar or DNS provider and add an A record:

| Setting | Value |
|---------|-------|
| Type | A |
| Name/Host | `voice` (or `@` for root domain) |
| Value/Points to | Your server's IP address (e.g., `203.0.113.50`) |
| TTL | 300 (or default) |

<Note>
DNS changes can take anywhere from a few minutes to 48 hours to propagate, though most changes take effect within 5-30 minutes. You can check if your DNS has propagated using tools like [dnschecker.org](https://dnschecker.org).
</Note>

### Verify DNS Propagation

Before proceeding, verify that your domain points to your server:

```bash
nslookup voice.yourcompany.com
```

You should see your server's IP address in the response.

## Step 2: Quick Setup (Recommended)

Once your DNS is configured, run the automated setup script that handles the rest.

<Note>
You must be at the same place where you had run `setup_remote.sh` from. The directory should contain `dograh/` with the artifacts that got created when `setup_remote.sh` was run.
</Note>
<Note>
You must not move the `dograh/` directory to a different location after running `setup_custom_domain.sh`, since we set up auto certificate renewal script as certbot renewal hook pointing to the `dograh/` directory.
</Note>

```bash
curl -o setup_custom_domain.sh https://raw.githubusercontent.com/dograh-hq/dograh/main/scripts/setup_custom_domain.sh && chmod +x setup_custom_domain.sh && sudo ./setup_custom_domain.sh
```

The script will prompt you for:
- Your domain name
- An email address for Let's Encrypt notifications

It will automatically:
- Verify DNS configuration
- Install Certbot
- Generate Let's Encrypt SSL certificates
- Update nginx configuration
- Configure automatic certificate renewal
- Restart Dograh services

Once complete, your application will be available at `https://voice.yourcompany.com`.

<Note>
If you prefer to set things up manually, continue with the steps below.
</Note>

## Manual Setup

If you prefer to configure everything manually, follow these steps instead of using the automated script.

### Install Certbot

Certbot is the official Let's Encrypt client that automates SSL certificate generation.

**Ubuntu/Debian:**

```bash
sudo apt update
sudo apt install certbot -y
```

**Amazon Linux/RHEL:**

```bash
sudo yum install certbot -y
```

### Stop Dograh Services

Before generating certificates, stop the running Dograh services to free up port 80:

```bash
cd dograh
sudo docker compose --profile remote down
```

### Generate SSL Certificates

Run Certbot to obtain SSL certificates for your domain:

```bash
sudo certbot certonly --standalone -d voice.yourcompany.com
```

Replace `voice.yourcompany.com` with your actual domain name.

Certbot will:
1. Verify that you control the domain
2. Generate SSL certificates
3. Store them in `/etc/letsencrypt/archive/voice.yourcompany.com/`

<Note>
You'll be prompted to enter an email address for renewal notifications and agree to the terms of service.
</Note>

### Copy Certificates to Dograh Directory

Copy the generated certificates to the dograh certs directory:

```bash
cd dograh
sudo cp /etc/letsencrypt/archive/voice.yourcompany.com/fullchain1.pem certs/local.crt
sudo cp /etc/letsencrypt/archive/voice.yourcompany.com/privkey1.pem certs/local.key
sudo chmod 644 certs/local.crt certs/local.key
```

### Update nginx Configuration

Update the nginx configuration to use your domain name. Open the nginx configuration file:

```bash
nano dograh/nginx.conf
```

Update the `server_name` directive with your domain:

```nginx
server {
    listen 443 ssl;
    server_name voice.yourcompany.com;

    ssl_certificate     /etc/nginx/certs/local.crt;
    ssl_certificate_key /etc/nginx/certs/local.key;

    # ... rest of the configuration remains the same
}
```

### Add environment variable

Replace `BACKEND_API_ENDPOINT` environment variable the `docker-compose.yaml` with your custom domain with the scheme.

### Start Dograh Services

Start Dograh with the updated configuration:

```bash
cd dograh
sudo docker compose --profile remote up -d --pull always
```

### Access Your Application

Your application is now available at:

```
https://voice.yourcompany.com
```

You should see a valid SSL certificate (green padlock) in your browser.

### Set Up Certificate Renewal

Let's Encrypt certificates expire after 90 days. Set up automatic renewal.

Create a renewal hook script that copies the new certificates:

```bash
sudo nano /etc/letsencrypt/renewal-hooks/deploy/dograh-reload.sh
```

Add the following content (replace paths as needed):

```bash
#!/bin/bash
# Copy renewed certificates to dograh certs directory
cp /etc/letsencrypt/archive/voice.yourcompany.com/fullchain1.pem /home/ubuntu/dograh/certs/local.crt
cp /etc/letsencrypt/archive/voice.yourcompany.com/privkey1.pem /home/ubuntu/dograh/certs/local.key
chmod 644 /home/ubuntu/dograh/certs/local.crt /home/ubuntu/dograh/certs/local.key

# Restart nginx to load new certificates
cd /home/ubuntu/dograh
docker compose --profile remote restart nginx
```

Make the script executable:

```bash
sudo chmod +x /etc/letsencrypt/renewal-hooks/deploy/dograh-reload.sh
```

Test that renewal works:

```bash
sudo certbot renew --dry-run
```

## Troubleshooting

### Certificate Generation Fails

If Certbot fails to generate certificates:

1. **Port 80 blocked**: Ensure port 80 is open in your firewall and no service is using it
2. **DNS not propagated**: Wait for DNS changes to propagate and verify with `nslookup`
3. **Rate limits**: Let's Encrypt has rate limits. If you've exceeded them, wait before retrying

### SSL Certificate Errors in Browser

If you see SSL errors after setup:

1. Verify the certificates were copied correctly: `ls -la dograh/certs/`
2. Check that `nginx.conf` points to `/etc/nginx/certs/local.crt` and `/etc/nginx/certs/local.key`
3. Restart the nginx container: `sudo docker compose --profile remote restart nginx`

### WebRTC Connection Issues

If voice calls don't connect after domain setup:

1. Ensure TCP/UDP ports 3478, 5349, and UDP 49152-49200 are still open
2. Update the `.env` file with your domain name if needed for TURN server configuration
