Bot config: eventMode='fetch', code='support_bot'. If the bot is alive on B24 (chats receive messages, im.bot.list lists it) the most common cause is B24-side event-subscription decay — run POST /v1/bots/42/resubscribe first (lightweight, preserves openline / WELCOME_BOT bindings). If that does not help, verify: (1) eventMode is 'fetch' (current: 'fetch'); (2) your OAuth app's INSTALL event handler responded 200 to Bitrix24; (3) the bot was added to a chat where messages are being sent (it must be a participant for chat-message events); (4) only if all of the above are confirmed — try POST /v1/bots to re-register (destroys openline bindings; last resort)."
