What have I done?
When I go the error first time, I tried to update the PHP version 7.3 and it said Owncloud X is not compatible with php 7.3. So I reinstalled the php version 7.2.34 and got that kind of issue. Help me

You tried to install an outdated version, go with the current 10.7 from Download Server Packages - ownCloud and php 7.3 or even 7.4

Thank you I will try

Hi, after I upgraded to the Owncloud 10.7 and PHP 7.4.19, I still got the HTTP Error 599.

Here is the error log for httpd:

Please provide your owncloud.log as it was requested in the issue template. HTTP 5xx errors are application errors, so they would not show up in the webserver log.

Look for strings like ‘Exception’, most probably this shows the issue.

Thank you for your response. This is my owncloud log.

My best guess is, that you omit to install some required php modules.

Hi I am sorry for the busy. Can I get some suggestion for the issue? Thank you.

You did not provide any module versions so the list above is not helpful.

In general, when it comes to php:

  • Use the very same version for the apache module and the CLI version
  • You must install the php modules for the required version (e.g. php74-php-xml for php 7.4)

I’d recommend using php 7.4 from the epel repository. There are various guides on the web, such as How To Install PHP 7.4, 7.3 & 7.2 on CentOS 7 - TecAdmin how to get this repository working

Thank you for your reply. Now, I am using PHP 7.4 and installed all the modules. But the issue still persist. Have you found any trace in below owncloud.log?

This is an outdated log with your previous configuration. Please send recent Exceptions from when you tried logging in

BTW, how about using a current version, instead of fiddling with an outdated one?

Sorry for infromation. The issue was not solved with current version.

I think this may help to you. If anything you need, please let me know.
Thank you for your help. Appreciate it.

Well, this is a new one. Is the file config.php present and accessible?

Yes Sir. The config.php is present in the respective directory. But the permission is rw-r----- and owned by “root”. Is it because of this?

This is my config file.

<?php $CONFIG = array ( 'instanceid' => 'ocn6yq5mjmgh', 'passwordsalt' => '1gZUXN8xhS77ElB6uG2KAhc+I9ZfJX', 'secret' => 'YMTpoiY+O4MXrT0ci7HzHneJ139Ghwy4BgMfp3IiDVFIgpqd', 'trusted_domains' => array ( 0 => 'server IP', 1 => 'www.example.com', ), 'datadirectory' => '/var/www/html/owncloud/data', 'overwrite.cli.url' => 'https://www.example.com', 'dbtype' => 'sqlite3', 'version' => '10.7.0.4', 'logtimezone' => 'UTC', 'installed' => true, 'loglevel' => 2, 'maintenance' => true, );

YES! It must be as all other files owned by user apache[1] and be writable.

[1] AFAIK, on CentOS the web-server runner is apache. But please verify this.
