后端使用MongoDB启动了一个非常简单的登录和注册应用程序。在Google云端上用kubernetes运行了该网站，但无法正确设置api请求。我从nginx收到502错误的网关。该网站位于：http://35.188.82.6 和github repo位于：https://github.com/damonleelcx/PureSign
“ http：//10.0.x.xx:3000/api/users/register”与google云服务器IP“ 35.188.82.6”不匹配。顺便，后端express服务器正在localhost上搭的。
请帮忙~~~谢谢!!!
下面是一些nginx报错的logs
