Asp.net Asp Net Core Nginx多域的重复侦听错误

我正在尝试在Linux上托管多个具有不同域的ASP NET核心站点，卸载18.04并使用nginx作为反向代理

我得到的错误是“80的重复监听选项”。此错误的原因是什么？如何解决此错误

默认的nginx配置为：

server {

    listen 80;

    server_name domain1.com www.domain1.com;

    location / {
            proxy_pass         http://localhost:5000;
            proxy_http_version 1.1;
            proxy_set_header   Upgrade $http_upgrade;
            proxy_set_header   Connection keep-alive;
            proxy_set_header   Host $host;
            proxy_cache_bypass $http_upgrade;
            proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header   X-Forwarded-Proto $scheme;
    }

}

server {

    listen 80;

    server_name domain2.com domain2.com;

    location / {
            proxy_pass         http://localhost:5005;
            proxy_http_version 1.1;
            proxy_set_header   Upgrade $http_upgrade;
            proxy_set_header   Connection keep-alive;
            proxy_set_header   Host $host;
            proxy_cache_bypass $http_upgrade;
            proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header   X-Forwarded-Proto $scheme;
    }

}
