AIO apache unhealthy

I installed a new nextcloud instance with the aio container. All went well so far but there is one problem that worries me a bit.

Nextcloud seems to be up and running and I can upload files without problems.
But the nextcloud-aio-apache container is always shown as unhealthy even though the webserver is up and running. I did not notice any major issues other than the instance became unresponsive and containers had to be restarted once after switching between some menus.

On the AIO page everything seems normal:

Looking at the container logs in portainer I see the following which doesn’t look very helpful:

I am a bit worried I could run into problems further down the road so I would appreciate some help what could be the issue.

I am running Nextcloud on Oracle Linux 9.2

EDIT: I am running Nextcloud behind Nginx Proxy Manager which is running on another host if this is relevant in any way.

My docker compose looks like this:

services:
        nextcloud:
          image: nextcloud/all-in-one:latest
          restart: always
          container_name: nextcloud-aio-mastercontainer
