How to deploy a Telegram Bot with Nginx reverse proxy

I developed a Telegram bot with the python-telegram-bot library and now i want to deploy it in my server, so i setup a webhook(following the Official Wiki) but when i try to communicate with my bot i don't get any reply.

This is the source of the bot:

def main():
   PRIVTOKEN = "1134xxxx"
   updater = Updater(PRIVTOKEN)

   dp = updater.dispatcher

   dp.add_handler(CommandHandler("start", start))
   # ...

   updater.start_webhook(listen='127.0.0.1',
                         port=8843,
                         url_path=PRIVTOKEN)
   updater.bot.set_webhook(webhook_url='https://example.com/' + PRIVTOKEN,
                           certificate=open("cert.pem", "rb"))
   print("bot started")
   updater.idle()

the nginx config file:

server {
  listen 443 ssl;
  server_name example.com;


  location /1134xxxx {
     proxy_pass http://127.0.0.1:8443;
  }
}

The netstat status:

sudo netstat -an | grep 8843
tcp        0      127.0.0.1:8843            0.0.0.0:*               LISTEN

No other errors where logged either by the bot(i've enabled the error logs) or by nginx(access/error.log)

I’ve also added a custom rule for 8843 port in the firewall.

Telegram supports only https requests. note this.

my nginx config: 

server {
        listen 80;
        listen 443 ssl;
        server_name example.com www.example.com;
        ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
        if ($scheme = http) {
            return 301 https://$server_name$request_uri;
        }
    location / {
            proxy_set_header Host $http_host;
            proxy_redirect off;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Scheme $scheme;
            proxy_pass http://localhost:5005/;
    }
}
