Nginx reverse proxy 未找到Nextcloud版本20、404

我在这里发帖是因为我不知道该怎么办。 我的配置包括docker compose和nextcloud应用程序以及db。我还有另一个nginx容器作为反向代理。在版本19中，一切运行正常。这个问题出现在我升级了nextcloud应用程序（现在20）的映像之后。 我的问题是我得到了404https://my-domain/nextcloud/ . 经过几个小时的调试，我删除了docker compose，然后再次运行它（没有代理）。 一切都很好。 启动反向代理并将nextcloud应用程序配置为仅使用https后，问题又出现了

这是我的Ngnix代理配置，希望有人能发现问题并帮助我：
