Permission Issues on Some Systems

the relay may not have permissions to read and write to the database. To fix this, you can change the permissions of the database folder:

sudo chmod -R 777 /path/to/db

7. Serving over nginx (optional)

install nginx:

sudo apt-get update
sudo apt-get install nginx

You can serve the relay over nginx by adding the following configuration to your nginx configuration file located at /etc/nginx/sites-available/default:

server {
    listen 80;
    server_name yourdomain.com;

    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

Replace yourdomain.com with your actual domain name.

After adding the configuration, restart nginx:

sudo systemctl restart nginx

8. Install Certbot (optional)

If you want to serve the relay over HTTPS, you can use Certbot to generate an SSL certificate.

sudo apt-get update
sudo apt-get install certbot python3-certbot-nginx

After installing Certbot, run the following command to generate an SSL certificate:

sudo certbot --nginx

Follow the instructions to generate the certificate.

8. Access the relay

Once everything is set up, the relay will be running on localhost:8080 or your domain name if you set up nginx.
