I tried to reinstall redis but i can make it work.. 
Any hints?

Is Redis running? What is the output of:
sudo systemctl status redis-server

and:

(type as root from CLI): redis-cli -h 127.0.0.1 -p 6379 -a <your-redis-password>

(The Redis console should show) redis 127.0.0.1:6379>
Type: PING
The answer should be: PONG

If above is TRUE, correct your entry for Redis inside NC’s conf-file:

  'redis' => 
  array (
    'host' => '127.0.0.1',
    'port' => 6379,
    'timeout' => 0,
    'password' => '<your-redis-password>',
    'dbindex' => 0,
  ),

Thank you. That might be a part of the problem.
Redis is not found.

I reinstalled it for the third time. Now it is working!
