Before clicking submit: Please check if your query is already addressed via the following resources:

• Official documentation (searchable and regularly updated)
• How to topics and FAQs
• Forum search

(Utilizing these existing resources is typically faster. It also helps reduce the load on our generous volunteers while elevating the signal to noise ratio of the forums otherwise arising from the same queries being posted repeatedly).

Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can.

The Basics

• Nextcloud Server version (e.g., 29.x.x):
  • 32.0.5

  • Ubuntu 24.04
• Web server and version (e.g, Apache 2.4.25):
  • nginx 1.24.0

  • nginx 1.24.0
• PHP version (e.g, 8.3):

  • yes
• When did this problem seem to first start?

• Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
  • bare metal (zip file)
• Are you using CloudfIare, mod_security, or similar? (Yes / No)
  • no

Summary of the issue you are facing:

There are several log entries with this message. Every time the web interface is opened, this logs arise. I feel it is slowing down my installation performance. Is it possible that this is the cause of the poor performance I’m experiencing (it seems yes, at first)?

Steps to replicate it (hint: details matter!):

1. wget https://download.nextcloud.com/server/releases/latest.zip
   unzip latest.zip
   sudo mv ~/Downloads/nextcloud/* /var/www/nextcloud/
   sudo chown -R www-data:www-data /var/www/nextcloud

2. config vitual host on nginx (I don’t feel it matters here)

3. Proceed to the URL and finish installation through the web installer.

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.
