     - Node 22+ + custom fetch/proxy can trigger immediate abort behavior if AbortSignal types mismatch.
     - Some hosts resolve `api.telegram.org` to IPv6 first; broken IPv6 egress can cause intermittent Telegram API failures.
+    - If logs include `TypeError: fetch failed` or `Network request for 'getUpdates' failed!`, OpenClaw now retries these as recoverable network errors.
+    - On VPS hosts with unstable direct egress/TLS, route Telegram API calls through `channels.telegram.proxy`:
+
+```yaml
+channels:
+  telegram:
+    proxy: socks5://user:pass@proxy-host:1080
+```
+
+    - If DNS/IPv6 selection is unstable, force Node family selection behavior explicitly:
+
+```yaml
+channels:
+  telegram:
+    network:
+      autoSelectFamily: false
+```
+
+    - Environment override (temporary): set `OPENCLAW_TELEGRAM_DISABLE_AUTO_SELECT_FAMILY=1`.
     - Validate DNS answers:
