Troubleshooting SSL Issues with Telegram Bot Webhook

I’m having trouble setting up a webhook for my Telegram bot. I created a small script on my website, but when I try to set the URL as the webhook, I keep getting an SSL error.

Here’s what I’ve tried so far:

  1. Setting the webhook URL directly
  2. Adding a self-signed certificate (which changed has_custom_certificate to true)

Unfortunately, both attempts resulted in the same SSL error. I’m not sure what I’m missing or doing wrong.

Has anyone encountered a similar issue? Any suggestions on how to properly set up the webhook and resolve this SSL problem? I’d really appreciate some guidance on troubleshooting this.

# Example code snippet (not actual, just for illustration)
import telebot

bot = telebot.TeleBot('YOUR_BOT_TOKEN')

def set_webhook():
    webhook_url = 'https://your-domain.com/bot-webhook'
    certificate_path = 'path/to/your/certificate.pem'
    
    result = bot.set_webhook(url=webhook_url, certificate=open(certificate_path, 'r'))
    print(f'Webhook set: {result}')

set_webhook()

Thanks in advance for any help!

I’ve encountered similar SSL issues with Telegram webhooks before. One crucial aspect often overlooked is ensuring your SSL certificate is valid and recognized by Telegram’s servers. Self-signed certificates can be tricky and aren’t always accepted.

Have you considered using a free SSL certificate from Let’s Encrypt? They’re widely recognized and can solve many SSL-related problems. Additionally, double-check that your server’s SSL configuration is correct and up-to-date.

Another potential issue could be your server’s firewall settings. Make sure port 443 is open and properly configured to allow incoming webhook requests from Telegram.

If you’re still stuck, you might want to try using ngrok for testing. It provides a secure tunnel to your localhost and can help isolate whether the problem is with your SSL setup or something else in your environment.

hey man, i had the same issue. wat fixed it for me was using a proper SSL cert from a trusted provider. self-signed ones are iffy with telegram.

check ur server config too. make sure its using the latest TLS version. telegram can be picky.

also, try using ngrok for testing. it helped me figure out if the problem was my SSL or sumthin else.

I’ve been through this SSL headache with Telegram bots too. What finally worked for me was using a proper SSL certificate from a trusted provider. Self-signed certs are hit-or-miss with Telegram.

Check your server’s SSL configuration. Make sure it’s using the latest TLS version and strong ciphers. Telegram can be picky about this.

Also, verify your domain’s DNS settings. Sometimes a misconfigured DNS can cause SSL validation issues.

If you’re on shared hosting, reach out to your provider. They might have specific requirements or restrictions for setting up webhooks.

Lastly, try testing with curl to see if you can hit your webhook endpoint successfully. This can help isolate if it’s a Telegram-specific issue or a general SSL problem on your server.
