从昨天开始，我有一个“ 502 Bad Gateway nginx / 1.13.12”。我不知道该如何解决该问题。我在docker上使用API平台2.2.5，周一一切正常。我当时在做项目的反应部分（前部分），而没有接触php部分。
我不是真正的开发人员，我是心脏病专家，所以请放纵
我在localhost中。这是docker-compose配置：

这是“ docker ps -a”

我在计算机上重新启动了docker，并启动了“ docker-compose up -d”，但它没有任何改变。
这是新的“ docker ps -a

如果我的php代码有问题，如何在没有symfony调试栏的情况下找到它？
