aws 克隆的 ec2 只顯示 nginx 預設頁面，為什麼？

Question

我有一個正在運行的實例，可以在 aws 上正確顯示網站。經營該網站所包含的內容django, nginx, uwsgi包括elastic ip

我已經創建了實例的圖像。啟動實例，現在我有第二個實例，與第一個實例相同。

第二個實例就正常了floating ip。當我在瀏覽器中輸入 IP 時，我希望也能看到我的網站，否則載入時間很長，直到超時，因為我還沒有進行任何配置site-available。

不管怎樣，我只能看到nginx歡迎頁面。我去了site-available，將 ip 輸入到server_name，還設定了一個dns名稱subdomain。更改後，我重新啟動了uwsgi。

我嘗試在瀏覽器上使用ip和subdomain，但仍然顯示nginx歡迎頁面。甚至沒有錯誤。

有人知道為什麼或建議我嘗試什麼嗎？

它們都是相同的設置，難道不能正常工作嗎？

PS 然後我嘗試將elastic ip第一個實例移到第二個實例...我在瀏覽器中使用了第一個實例的網域...然後我的網站彈出而不是nginx歡迎頁面

site-available對於完美運行的原始實例

    }




    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/subdomain.domain.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/subdomain.domain.com/privkey.pem; # managed by Certbot

    if ($scheme != "https") {
        return 301 https://$host$request_uri;
    } # managed by Certbot


}

至於第二個實例...我更改了server_name並且我嘗試包含和排除ssl但結果相同

這是第二個實例的配置
