 1. `revbotservice.php` 是长生命周期脚本，受目标 PHP 运行时参数影响（如 `max_execution_time`）。
 2. 若目标前置代理（Nginx/CDN）对长连接有限制，需要放宽超时。
 3. bothost 仅负责远程托管与状态监测；BOT 行为逻辑仍由 PHPDTS 原生 `revbot` 代码执行。

+## 故障诊断
+
+- 状态中 `err` 持续增长时，查看汇总下方 `last_error`，可直接看到最近一次 HTTP/网络错误详情。
+- 若出现类似 `Tunnel connection failed: 403 Forbidden`，通常是环境代理劫持导致，请确认 `disable_env_proxy=true`。
+- 若出现证书错误，可先确认站点证书链；仅在临时测试中可设 `insecure_skip_tls_verify=true`。
+
+- 若 `last_error` 中包含 `include(...common.inc.php): failed to open stream` 等报错，通常是目标站 `bot/revbotservice.php` 在 Web 环境下工作目录不正确；本仓库已修复为基于脚本目录计算 GAME_ROOT。
