在同一主机和同一端口上的 NGINX 中使用多个服务器块

我想配置服务器，以便服务器的根目录提供一些静态文件，这些文件是特定的端点，/nextcloud 为同一域上的 nextcloud 提供服务。

这是我的 nginx.conf -

worker_processes  8;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       80 http2;
        listen [::]:80 http2;
        server_name  localhost;
        root   /srv/http/;
        location / {
            index  index.html index.php;
            try_files $uri $uri/ =404;
            autoindex on;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
    }
    include /etc/nginx/sites-enabled/*;
}

这是我的 /etc/nginx/sites-enabled/nextcloud.conf

upstream php-handler {
    server unix:/run/nextcloud/nextcloud.sock;
}

server {
    listen 80;
    listen [::]:80;
    server_name nextcloud;

    root /usr/share/webapps/;

    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }

    location ^~ /.well-known {
        location = /.well-known/carddav { return 301 /nextcloud/remote.php/dav/; }
        location = /.well-known/caldav  { return 301 /nextcloud/remote.php/dav/; }

        location /.well-known/acme-challenge    { try_files $uri $uri/ =404; }
        location /.well-known/pki-validation    { try_files $uri $uri/ =404; }

        return 301 /nextcloud/index.php$request_uri;
    }

        }

        location ~ \.(?:css|js|svg|gif|png|jpg|ico|wasm|tflite)$ {

            expires 6M;         # Cache-Control policy borrowed from `.htaccess`
            access_log off;     # Optional: Don't log access to assets

            location ~ \.wasm$ {
                default_type application/wasm;
            }
        }

        location ~ \.woff2?$ {
            try_files $uri /nextcloud/index.php$request_uri;
            expires 7d;         # Cache-Control policy borrowed from `.htaccess`
            access_log off;     # Optional: Don't log access to assets
        }

        location /nextcloud/remote {
            return 301 /nextcloud/remote.php$request_uri;
        }

        location /nextcloud {
            try_files $uri $uri/ /nextcloud/index.php$request_uri;
        }
    }
}

问题是这个配置不起作用。使用此配置，当我尝试访问 /nextcloud/ 时得到 404。

如果我在 nginx.conf 中禁用静态文件服务器块，我可以访问 /nextcloud/，但是我无法访问我的静态文件。如何配置使两者都在同一主机和同一端口上工作？
