Internal Server Error after login // nginx MariaDB php redis fail2ban ufw

ℹ️ Support
1

Hi guys,
please check my problem below. Yesterday I installed NextCloud with a step by step guide (https://decatec.de/home-server/nextcloud-auf-ubuntu-server-20-04-lts-mit-nginx-mariadb-php-lets-encrypt-redis-und-fail2ban/). Everything worked fine. After adding users and groups in NextCloud i couldn’t login anymore.

I am a normal “windows” guy, so it’s my first time working with servers and ubuntu. I try to understand as much as possible, but it’s a lot of stuff to learn/understand :slight_smile:

Thanks in advance!

Nextcloud version 19.0.0.12
Operating system and version : Ubuntu 20.04
Apache or nginx version: nginx version: nginx/1.19.0
PHP version : PHP 7.4.3

The issue you are facing:

Everytime I try to login I’ll get the error message “internal server error”.
It doesn’t matter if it’s a normal user or admin.

I’ve checked chmod on RedisFactory.php (-rw-r–r-- 1 www-data www-data 3282 May 26 10:08 RedisFactory.php)

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

Steps to replicate it:

Any ideas?

I’ve my back on the wall. Do you need more information to be able to help?

4

Comment out the redis part of your config and try it again. Also parsing your config could have a problem.

'filelocking.enabled' => 'true',

should be:

'filelocking.enabled' => true,

5

Thank you for your answer,

as first I tried to change ‘true’ to true, but without effect.
After this I commented the code out as follows:

...
  'filelocking.enabled' => true,
  'memcache.locking' => '\\OC\\Memcache\\Redis',
/*  'redis' => array (
    'host' => '/var/run/redis/redis-server.sock',
    'port' => 0,
    'timeout' => 0.0,
  ),
*/
  'auth.bruteforce.protection.enabled' => false,
...

Unfortunatelly nothing helped.
