我在Nginx中为一个运行在localhost的应用程序配置反向代理时遇到了问题。

Question

我已经得到了 翼龙 在运行Ubuntu v18.04.4 LTS的Digital Ocean液滴上设置。大约一年前，我把它和Nginx一起设置，设置了A记录（panel.example.com），并且在使用Let's Encrypt SSL证书的情况下工作得很好。

几天前，我决定在Nginx上设置 休息室，是一个自我托管的Web IRC客户端。默认情况下，它运行在9000端口。 我按照他们的建议 说明，改变了他们帮助IRC频道上的人推荐的一些东西。与翼龙面板不同的是，我希望这个显示在我的个人域名上。所以，我设置了我的A记录指向我的DO droplet，主机值为 irc因此，它将显示在 irc.yash.gg. 然后，我使用acme.sh在独立模式下生成Let's Encrypt密钥。然后，我将下面的配置添加到 /etc/nginx/sites-available/thelounge.conf，并将其链接到 /etc/nginx/sites-enabled/thelounge.conf. 但不知道为什么，用下面的配置，它开始重定向到 "你已经正确设置了nginx "页面。而现在，几天后，我被引导到我的翼龙面板，而不是panel.sneakycraft.com。

我完全迷茫了，我不明白这是怎么回事。我真的很感激一些帮助。请让我知道，如果我可以提供任何其他帮助诊断这个问题。

谢谢！我有一个翼龙。
