My Telegram bot has stopped reacting whenever a new user registers on my site. API calls appear to go out, yet the bot never receives or processes the update, so subscribers are left without the welcome or onboarding message they expect. The core problem is that the bot is simply not receiving updates from my server even though it should be alerted to “website status changes”—specifically every new user registration. Here’s what I can provide the moment we start: current PHP / Node endpoint code that pushes the update, the bot token, the existing webhook logic, and server access for testing. I need you to trace where the breakdown occurs and restore reliable, real-time delivery. A quick review of the webhook configuration, SSL, and any Telegram API rate or security settings will likely be required, followed by adjustments to the callback handler so it parses and acknowledges each registration event correctly. Successful completion means that as soon as someone registers, the bot receives the payload, sends out the predefined welcome message, and logs the transaction without errors. If you have solid experience with Telegram Bot API, webhooks, and server-to-bot messaging, I’m ready to get this resolved right away.
