The issue you are facing:
I deleted my nextcloud.log to have a clean log in my Nextcloud.
Now i can’t access my files anymore.
Redis is encountering errors.

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

Steps to replicate it:

  1. Delete Nextcloud.log

The output of your Nextcloud log in Admin > Logging:

Nothing deleted it <.<

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

<?php $CONFIG = array ( 'instanceid' => '****', 'passwordsalt' => '****', 'secret' => '****', 'trusted_domains' => array ( 0 => '****', 1 => '****.de', 2 => 'www.****.de', 3 => 'cloud.****.de', ), 'datadirectory' => '/var/nextcloud/data', 'dbtype' => 'mysql', 'version' => '16.0.0.9', 'csrf.disabled' => true, 'overwrite.cli.url' => 'https://****.de/nextcloud', 'dbname' => '****', 'dbhost' => '****', 'dbport' => '****', 'dbtableprefix' => 'oc_', 'dbuser' => '****', 'dbpassword' => '****', 'installed' => true, 'maintenance' => false, 'theme' => '', 'loglevel' => 2, 'memcache.local' => '\\OC\\Memcache\\Redis', 'redis' => array ( 'host' => 'localhost', 'port' => 6379, ), 'memcache.locking' => '\\OC\\Memcache\\Redis', 'cache_path' => '/var/nextcloud/data/usercache', 'mail_domain' => '****.de', 'mail_from_address' => 'info', 'mail_smtpmode' => 'smtp', 'mail_sendmailmode' => 'smtp', 'mail_smtpauth' => 1, 'mail_smtpport' => '25', 'mail_smtphost' => '127.0.0.1', 'mail_smtpname' => '****', 'mail_smtppassword' => '****', 'mail_smtpauthtype' => 'PLAIN', 'mysql.utf8mb4' => true, 'ldapIgnoreNamingRules' => false, 'ldapProviderFactory' => 'OCA\\User_LDAP\\LDAPProviderFactory', 'app_install_overwrite' => array ( 0 => 'mail', 1 => 'passman', 2 => 'end_to_end_encryption', 3 => 'radio', ), 'data-fingerprint' => '****', );

The Redis server is used for file locking, therefore this could be an explanation for the described problem. Make sure that the Redis server is up-and-running to prevent such a problem in the future.

My Redis Server is running and it worked before i deleted the nextcloud.log, i switched to apcu now and everything is working again…

The existence of the Nextcloud log file has definitely no influence on the function of the Redis server. To be honest, I would assume that you’ve changed something else which has caused a Redis server problem.

fixed by adding redis:x:113:www-data to my /etc/group

If someone is interested, here is my new working config.php using APCu and Redis in combination:
