Failed authorisation procedure

No i did not move, because:

that means redis is not working.

did you try to disable redis in your config? just remove:

  'memcache.local' => '\\OC\\Memcache\\Redis',
  'filelocking.enabled' => 'true',
  'memcache.distributed' => '\\OC\\Memcache\\Redis',
  'memcache.locking' => '\\OC\\Memcache\\Redis',
  'redis' =>
  array (
    'host' => '/var/run/redis/redis.sock',
    'port' => 0,
    'timeout' => 0,
    'dbindex' => 0,
  ),

of course mak ea backup of the orginal file before changing something.
