+# Channel Troubleshooting
+
+## Overview
+
+This guide provides diagnostic guidance for resolving channel configuration issues in OpenClaw.
+
+## Diagnostic Commands
+
+Start with these commands:
+
+```bash
+openclaw doctor
+openclaw channels status --probe
+```
+
+The `channels status --probe` command prints warnings when it can detect common channel misconfigurations, and includes small live checks (credentials, some permissions/membership).
+
+## Supported Channels
+
+Three primary channels have dedicated troubleshooting sections:
+
+- Discord
+- Telegram
+- WhatsApp
+
+## Telegram-Specific Solutions
+
+### Network Request Failures
+
+IPv6 DNS problems may cause `HttpError` messages for 'sendMessage' or 'sendChatAction'.
+
+**Solution:** Force IPv4 or enable IPv6 support.
+
+### Command Configuration Issues
+
+When `setMyCommands failed` appears in logs, verify outbound HTTPS and DNS reachability to `api.telegram.org`. This frequently fails on restricted VPS environments or proxy setups.
