在Coolify上自托管n8n时队列模式无法正常工作

我在Coolify上自托管n8n，尝试启用队列模式，已严格遵循官方Docker配置指引并多次验证，但任务执行仍由主n8n实例直接处理，未进入队列。此外，点击执行工作流时加载动画不会自动更新，仅刷新页面才会停止（非队列模式下无此问题）。

我的Docker Compose配置 #

当前异常现象 #

• 工作流可从UI正常运行，但任务明显由主n8n容器执行
• 点击执行工作流后，加载动画无状态更新，需手动刷新页面才会停止
• Redis容器无任何日志输出
• n8n主实例日志显示：Execution mode set to "queue"
• Worker容器日志无任何记录，完全未拾取工作流任务

怀疑问题点 #

• Coolify内部网络/路由配置异常
• n8n主实例未实际将任务推送至Redis队列

请问有谁成功在Coolify上配置并运行n8n队列模式吗？
