我将nginx.conf配置为将请求从Angular 2应用程序传输到tomcat应用程序。仍然有几个问题。我的nginx.conf如下：

worker_processes  1;
events {
worker_connections  1024;
}
http {
include       mime.types;
default_type  application/octet-stream;
sendfile        on;
keepalive_timeout  65;
server {
    listen          8082;
    root /;
    client_max_body_size 50M;
    location /images {
    root /var/www/rentoptimum;
    }
    location / {
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://localhost:4200/;
    }
    location /api/ {
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://localhost:8080/rentapp/;
    }
}
server {
    listen       8081;
    server_name  localhost;
    location / {
        root   html;
        index  index.html index.htm;
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
}
include servers/*;
}

网址localhost：8081正常工作，我看到“欢迎使用nginx”。Localhost：4200提供了角度应用。Localhost：8082无法打开localhost：4200，并且tomcat
的代理传递（http：// localhost：8080 / rentapp /
;）也不起作用。

Chrome上的错误堆栈如下：
