Nextcloud configuration

I was able to install Nextcloud from reForis, with Turris OS HBK, only in the overview I see this:

Actually, these errors are not new, but some are the same as a couple of years ago. It actually works the way I use it: installed it on /srv on an encrypted disk, left all default, entered among the allowed addresses the one for my ddns.
Two years ago, I removed them by following Nextcloud’s guides, but I no longer remember the steps.
Can anyone knowledgeable tell me how to improve this? Or better to ignore?

Hi,
Which line do you want to clean ? all of them ?
Are you using caldav for instance ? if no don’t care about these alerts

Starting with the fact that I understand little about php, I would be interested in removing at least the first two alerts, which are nice and orange. I do not use CalDAV.

This normal security hardening is part of multiple threads in the www. Did you try and follow the links to the official documentation about them? :wink:

I am following. But I don’t know where to do this Hardening and security guidance — Nextcloud latest Administration Manual latest documentation.
What web server is used for Nextcloud on Turris OS?

EDIT: I’m here now, following the links. Two very simple changes to two configuration files. lighttpd also check nextcloud.

I got to the bottom: I am left with three warnings, which I cannot fix, because the php8 modules are missing: apcu (or redis or memcached), present in php7, sodium and imagick. Otherwise all gone.

In case someone else is try to fix the WebDAV warnings.

This is my configuration file https://clbin.com/jpGZr and this is the result:

I went crazy with it for a while yesterday, but I see no solution.

Edit: https://help.nextcloud.com/t/nextcloud-21-nodeinfo-and-webfinger/109423/35?page=2
From the last comment on the Nextcloud forum page, I found out that I have to delete the page data to see the result. It worked.

I was left only with the notice of those missing forms. I hope OpenWrt will add them, especially the one related to the local cache.
