Web Browser

If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.

PASTE

Web server / Reverse Proxy

The output of your Apache/nginx/system log in /var/log/____:

PASTE HERE

Configuration

Nextcloud

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

PASTE HERE

Apps

The output of occ app:list (if possible).

Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.
  • If screenshots are useful, feel free to include them.
    • If possible, also include key error output in text form so it can be searched for.
  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.

I have a very similar issue in NC32 attempting to access the Administrative Settings, Apps or App Update (when I click on the notification icon), see NC32 - Call to undefined function OC\Security\idn_to_utf8() , however the log error is different:

Call to undefined function OC\\Security\\idn_to_utf8() in file /usr/share/webapps/nextcloud/lib/private/Security/RemoteHostValidator.php line 38

This started within the last few days (I believe after the PHP 8.2 → 8.3 update). I was able to access the admin settings and update apps last week without issue.
