问题[cockpit](server)

我有一个服务器（Ubuntu-Server），带有一些基于 Docker 的服务器（Gitlab、Redmine）和 NGINX 作为代理。

gitlab.<myserver>    => NGINX -> <docker-net-ip>:port => Gitlab-container  
redmine.<myserver>   => NGINX -> <docker-net-ip>:port => Redmine-container
                                                         SQL-container  
                                                         Certbot  

这就像一个魅力。现在我想通过 Cockpit Web Service 扩展我的服务器：

cockpit.<myserver>   => NGINX -> localhost:9090       => Cockpit running on the server  
gitlab.<myserver>    => NGINX -> <docker-net-ip>:port => Gitlab-container  
redmine.<myserver>   => NGINX -> <docker-net-ip>:port => Redmine-container
                                                         SQL-container  
                                                         Certbot  

我为驾驶舱添加了一个额外的 NGINX 规则（对应于https://github.com/cockpit-project/cockpit/wiki/Proxying-Cockpit-over-NGINX），然后驾驶舱可用，但 Redmine 和 Gitlab 都没有。如果我删除规则，反之亦然。

在/etc/nginx/sites-available/和/etc/nginx/sites-enabled/中存储了以下 NGINX 规则：

gitlab.<我的服务器>

server {

    listen 80;
    listen [::]:80;

    server_name gitlab.<myserver>;

    location / {
        proxy_pass         http://<docker-net-ip>:port;
        proxy_buffering    off;
        proxy_set_header   X-Real-IP       $remote_addr;
    }
}

redmine.<我的服务器>

server {

    listen 80;
    listen [::]:80;

    server_name redmine.<myserver>;

    location / {
        proxy_pass         http://<docker-net-ip>:port;
        proxy_set_header   Host                $host;
        proxy_set_header   X-Real-IP           $remote_addr;
        proxy_set_header   X-Forwarded-for     $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto   $scheme;
    }
}

现在我添加了：
cockpit.<myserver>

server {
    listen         80;
    listen         443 ssl;

    server_name    cockpit.<myserver>;

    location / {
        # Required to proxy the connection to Cockpit
        proxy_pass https://127.0.0.1:9090;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-Proto $scheme;

        # Required for web sockets to function
        proxy_http_version 1.1;
        proxy_buffering off;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        # Pass ETag header from Cockpit to clients.
        # See: https://github.com/cockpit-project/cockpit/issues/5239
        gzip off;
    }
}

和/etc/cockpit/cockpit.conf

[WebService]
Origins = https://cockpit.<myserver> 127.0.0.1:9090
ProtocolHeader = X-Forwarded-Proto

[Log]
Fatal = /var/log/cockpit.log

[Session]
IdleTimeout=15

这里缺少什么？
