根据你提供的浏览器控制台日志，可以解读出以下信息：

• 页面访问路径：先尝试访问 http://192.168.16.80/dashboard/，然后通过 XHR 请求 /dashboard/header/（状态 200 成功），最后页面主动跳转到了 /dashboard/auth/login/。
• 关键现象：访问 Dashboard 首页后，被重定向到了登录页面（/auth/login/）。这通常意味着用户当前没有有效的认证会话（未登录或会话已过期），Horizon 强制要求重新登录。
  
  

可能的原因与排查方向1. 浏览器 Cookie / Session 问题

• 原因：之前的登录会话已过期，或者浏览器清除了 Cookie。
• 解决：清除浏览器缓存和 Horizon 相关的 Cookie，然后重新访问 /dashboard/，应该会直接显示登录页（而不是先跳转首页再重定向）。日志中显示的跳转是正常逻辑。
