Error 599 in owncloud client

I installed and configured Owncloud on an OVH shared server. I then started my transfer to upload the files from my computer to my Owncloud server.

Everything worked for a while, but now I get a server replied 599 broken to put https://...... All the files are in red! What’s going on? Here’s my configuration. Everything worked for a while, but now I get a 599 error. All the files are in red! What’s going on? Here’s my configuration :

Your server is very broken. There should be a crash log (not the same as the owncloud.log) somewhere in the server with information, but the usual reason is that the config.php can’t be loaded because of a syntax error, which causes the server to explode.

Pretty sure you need to fix your config.php file.

But what do I need to change in the config.php file?

<?php
$CONFIG = array (
  'instanceid' => 'xxxx',
  'passwordsalt' => 'xxxxxxxxx',
  'secret' => 'xxxxxx',
  'trusted_domains' => 
  array (
    0 => 'cloud.xxxxxx.com',
  ),
  'datadirectory' => '/home/xxxxx/owncloud/data',
  'overwrite.cli.url' => 'https://cloud.xxxxxxo.com',
  'dbtype' => 'mysql',
  'version' => '10.15.3.0',
  'dbname' => 'xxcc',
  'dbconnectionstring' => '',
  'dbhost' => 'xxxxx.mysql.db',
  'dbtableprefix' => 'oc_',
  'mysql.utf8mb4' => true,
  'dbuser' => 'xxxxxx',
  'dbpassword' => 'xxxxxxi203nqx5',
  'allow_user_to_change_mail_address' => '',
  'logtimezone' => 'UTC',
  'apps_paths' => 
  array (
    0 => 
    array (
      'path' => '/home/xxxxxx/owncloud/apps',
      'url' => '/apps',
      'writable' => false,
    ),
    1 => 
    array (
      'path' => '/home/xxxxx/owncloud/apps-external',
      'url' => '/apps-external',
      'writable' => true,
    ),
  ),
  'installed' => true,
);

Regarding the log file, there are many things marked, but I don’t know how to read it!
How to see errors in owncloud.log?

Are you sure you’re connecting to the right instance? If it’s broken you shouldn’t be able to even login. If you can access to the settings page at least that instance works, so it shouldn’t respond with any 599 error.

You can try to find the crash log, whose filename is formatted like crash-{date}.log, such as crash-2025-07-31.log. Note that it might contain sensitive information, but it will help to understand the reason of the crash.
