# Troubleshooting

- [My bot does not reply](https://help.bots.business/troubleshooting/bot-not-responding.md): Diagnose a Telegram bot that does not reply: check token, launch state, commands, pending input, groups, errors, and iterations.
- [Read errors and fix the failing command](https://help.bots.business/troubleshooting/errors.md): Read bot execution errors, jump to the failing command and line, and distinguish syntax checks from runtime and Telegram failures.
- [Fix slow commands and timeouts](https://help.bots.business/troubleshooting/performance.md): Diagnose slow commands and timeouts by separating BJS work, external requests, scheduled tasks, broadcasts, and quota limits.
