RASA_Deployment_on_VPS.md

Configuring Nginx

• Open /etc/nginx/nginx.conf
• Add this code block

server{
        listen 80;
        listen [::]:80;

        server_name  www.shivampip.com shivampip.com;
        location / {
            proxy_pass http://127.0.0.1:5005;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
      }
}

• server_name must be domain name. Not subdomain (it will not get ssl certificate)

Getting SSL certificate

• SSL certificate is required for Telegram connection.
• Self-signed SSL won't work here.
• Good doc: https://letsencrypt.org/getting-started/
• Follow it to generate SSL certificate for your domain: https://certbot.eff.org/

webhook_url: "https://www.shivampip.com/webhooks/telegram/webhook"
