Summary of the issue you are facing:

I have a running installation of Nextcloud AOI. Everything is running as it shoud except Im getting the multiplke errors like theses…

  • Error: Cannot connect to server

  • Could not check that the data directory is protected. Please check manually that your server does not allow access to the data directory. To allow this check to run you have to make sure that your Web server can connect to itself. Therefore it must be able to resolve and connect to at least one of its trusted_domains or the overwrite.cli.url. This failure may be the result of a server-side DNS mismatch or outbound firewall rule.

  • Your webserver is not set up to serve .js.map files. Without these files, JavaScript Source Maps won’t function properly, making it more challenging to troubleshoot and debug any issues that may arise.

  • Unable to run check for JavaScript support. Please remedy or confirm manually if your webserver serves .mjs files using the JavaScript MIME type. To allow this check to run you have to make sure that your Web server can connect to itself. Therefore it must be able to resolve and connect to at least one of its trusted_domains or the overwrite.cli.url. This failure may be the result of a server-side DNS mismatch or outbound firewall rule.

  • Could not check if your web server properly resolves the OCM and OCS provider URLs. To allow this check to run you have to make sure that your Web server can connect to itself. Therefore it must be able to resolve and connect to at least one of its trusted_domains or the overwrite.cli.url. This failure may be the result of a server-side DNS mismatch or outbound firewall rule.

I have the nginx reverse proxy set up as per the AOI instructions. The Apache2 port is set to 11001. Not sure what is missing or inconfigured.

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

Log entries

Nextcloud

Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.

PASTE HERE

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.
