Tailscale is connected but I get no replies What now

Check the basics:
Gateway is running: openclaw gateway status
Gateway health: openclaw status
Channel health: openclaw channels status
Then verify auth and routing:
If you use Tailscale Serve, make sure gateway.auth.allowTailscale is set correctly.
If you connect via SSH tunnel, confirm the local tunnel is up and points at the right port.
Confirm your allowlists (DM or group) include your account.
