Nextcloud version: 13.0.2
Operating system and version: CentOS 7
Apache or nginx version: Apache
PHP version: 7.2

The issue you are facing:

multiple files upload hangs after a while

Is this the first time you’ve seen this error? (Y/N): N

Steps to replicate it:

  1. try to upload a directory

The output of your Nextcloud log in Admin > Logging:

none

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

<?php
$CONFIG = array (
  'instanceid' => 'IID',
  'passwordsalt' => 'SALT',
  'secret' => 'SECRET',
  'trusted_domains' => 
  array (
    0 => 'SERVER_IP',
    1 => 'SERVER_FQDN',
  ),
  'datadirectory' => '/dir/data',
  'overwrite.cli.url' => 'https://MYIP/nextcloud',
  'dbtype' => 'mysql',
  'version' => '13.0.2.1',
  'dbname' => 'nextcloud',
  'dbhost' => 'localhost',
  'dbport' => '',

  'overwriteprotocol' => 'https',
  'maintenance' => false,
  'updater.release.channel' => 'stable',
  'updater.secret' => 'SECRET',
  'loglevel' => 2,
);

The output of your Apache/nginx/system log in /var/log/____:

nothing interesting

Every time I get also an entry in nextcloud logs look like this:

It’s a fresh install 13.0.1 updated today to 13.0.2 (because of vanishing progress bar) Can’t upload any bigger volume of files…
I have SELinux enabled but it doesn’t show any interesting entries in log. (actually doesn’t show any while using NC)
