FloodWait Error: Bot Blocked Due to Excessive Authorization Attempts on Startup
The Telegram bot is encountering a FloodWait error during startup caused by multiple rapid authorization attempts using the same bot token. Each unauthorized or repeated attempt triggers Telegram’s rate-limiting mechanism, specifically the auth.ImportBotAuthorization method, which results in a 420 FLOOD_WAIT_X exception. This exception mandates the bot to wait a specified number of seconds (e.g., 1658 seconds) before attempting to authenticate again.
This error causes the application to exit with code 1 repeatedly, especially when the bot is hosted on platforms that auto-restart on failure. Continual retries further increase the flood wait duration, effectively locking the bot out for extended periods.
Suggested Fix: Implement a flood wait handler to detect FloodWait exceptions and pause the bot execution for the required wait time before retrying. Also, minimize frequent restarts and avoid triggering bot authentication repeatedly within short intervals.
This issue occurs when the bot attempts to authorize too frequently within a short period, triggering Telegram's anti-spam mechanism. To prevent this, we should implement a FloodWait handler that respects the required delay before retrying. This will help avoid unnecessary downtime, especially on platforms with auto-restart enabled. A retry mechanism with asyncio.sleep(e.x) based on the FloodWait exception can solve this smoothly.
