使用 LE 集成设置 Traefik - 错误太多重定向/302

Question

我一直在关注 Traefik 和 LE 集成的示例以及 SmartHomeBeginner 上的示例，尽管我一直无法让 Traefik 通过 https 在子域上工作。我可以在带有端口号的 IP 地址上看到后端，但这并不理想。

当我在浏览器中查看 HTTPS 页面时，我不断收到 ERR_TOO_MANY_REDIRECTS 并且我已经确认在 Linux 中执行简单的 wget 失败并且我收到 302 错误并且在 20 之后出现重大失败重定向。

我看不出哪里错了...

我已经设法解决了我遗漏的问题，traefik.toml 和 docker-compose 文件都没有问题，唯一的问题是 Cloudflare 设置为 'Flexible'但必须设置为 'Off'，因为我正在尝试使用 LE 证书，然后就可以了。参考link：
