Docker-proxy 阻止容器在重启后启动

我有一台用作 NAS 的 PC，它运行 NextCloud 实例，作为一组通过 docker-compose 管理的 docker 容器，我将在下面提供 docker-compose.yml。我的问题是，即使我的所有容器都配置为“restart: always”，如果我重新启动 NAS，只有一个容器会尝试启动，并且实际上会无限期地保持“正在重新启动”状态。例如，我在进行一些更新后重新启动了我的 NAS，以下是输出$ docker ps：

CONTAINER ID        IMAGE                                    COMMAND                  CREATED             STATUS                          PORTS               NAMES
5679fcfe9174        jrcs/letsencrypt-nginx-proxy-companion   "/bin/bash /app/entr…"   5 weeks ago         Restarting (1) 18 seconds ago                       nextcloud-letsencrypt

如果我尝试使用启动所有容器，$ docker-compose up -d我会得到以下输出：

Starting nextcloud-mariadb ... error
Starting nextcloud-proxy   ... 

ERROR: for nextcloud-mariadb  Cannot start service db: container is marked for removal and cannot be started
Starting nextcloud-proxy   ... error

ERROR: for nextcloud-proxy  Cannot start service proxy: driver failed programming external connectivity on endpoint nextcloud-proxy (a73acdc99f7fb693a231ffd3b9cbb6d69a96176d41511c259c82a00dfab704a5): Error starting userland proxy: listen tcp 0.0.0.0:443: bind: address already in use

ERROR: Encountered errors while bringing up the project.

事实上，如果我使用以下方法查找开放端口，$ sudo netstat -tulpn | grep LISTEN我会得到类似的结果：

tcp        0      0 127.0.0.53:53           0.0.0.0:*               LISTEN      1341/systemd-resolv

在终止两个“docker-proxy”进程并通过重新启动 Docker 守护程序后，$ sudo systemctl restart docker我终于启动并运行了所有容器（包括另一个配置为“restart: always”但不是 NextCloud 实例的一部分的容器）。 我的问题是：如何让 Docker 在重启后自动启动所有容器无需手动终止两个“docker-proxy”实例并重新启动docker守护程序？我使用的操作系统是Ubuntu Server 20.04.1 LTS，我的Docker版本是19.03.13，内部版本4484c46d9d。这是我的NextCloud实例的docker-compose.yml：
