I’m having trouble setting up a webhook for my Telegram bot using a self-signed certificate. I created the certificate using the OpenSSL command below:
After generating the certificate and setting up the webhook, I’m not receiving any requests on my server. When I check my server logs, there are no entries showing that Telegram is trying to reach my webhook endpoint. The webhook appears to be configured but completely inactive.
I followed the official documentation for self-signed certificates but something seems to be wrong with my setup. Has anyone encountered similar issues with Telegram webhook configuration? What could be preventing the webhook from receiving any traffic at all?
Telegram’s servers won’t accept self-signed certificates unless they’re set up right. Make sure the CN (Common Name) in your certificate matches your webhook domain exactly - if it doesn’t match, Telegram will refuse to connect. That’s probably why you’re not getting any requests. Also check your firewall settings since it might be blocking connections on your webhook port. Try testing your webhook endpoint with curl to see if it’s a server config issue or something wrong with the Telegram setup.
Had the same issue with my Telegram bot. Turned out Telegram’s servers didn’t trust my certificate. Make sure your self-signed cert is installed correctly and accessible. Also check that your webhook URL is formatted right and reachable from the internet. Sometimes it’s just a DNS or network config problem blocking Telegram from hitting your server. I’d run a diagnostic to see if your server’s actually accessible from outside networks.
double-check that you uploaded the cert file when setting up your webhook - you need to include the .pem file in the certificate parameter when calling setWebhook. People forget this all the time and Telegram just ignores the webhook completely. also make sure your domain’s pointing to the correct IP since Telegram has to resolve it properly.
