Summary of the issue you are facing:

Hello, I am having a similar issue to imneedham, from his post he started in Nov 2024. I get the “Error occurred while checking server setup” message during the scan. Error appears after 1 minute of checking. This did not occur after an upgrade, I recently changed my Unraid flash drive to a new one but right before this started happening (I believe) I enabled the two-factor TOTP Provider app in Nextcloud. This app is working fine, as is the rest of Nextcloud. I’ve read raising the timeout value and clearing out the Nginx cache can help, but I don’t have a cache folder. I’m not sure where to start looking…

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

  1. Go to Nextcloud web > Admin settings > Overview
  2. Wait one minute.
  3. Error message appears.

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.

The error suggests that the Nextcloud container is unable to reach the configured overwrite.cli.url nor any of your configured trusted_domains.

May want to review those in your config and do some testing from inside the container using curl.
