I'm having trouble with Telegram integration in OpenClaw:
Issue:
- Telegram channel is configured with bot token
- Configuration shows: enabled: true, botToken is set
- But the bot doesn't respond to messages
What I've tried: - Added bot token via environment variable: OPENCLAW_TELEGRAM_BOT_TOKEN
- Restarted the service multiple times
- Started a conversation with the bot in Telegram
- Bot token is correct (verified from BotFather)
Current setup: - Service: OpenClaw on Zeabur
- Model: Gemini 2.5 Flash (working fine)
- Telegram: Not responding
Can you help me debug this?
