Hello again,

The problem has returned. I think everything is configured correctly. This time when i execute command:  
`sudo -u www-data crontab -l`

i get:

> OC\HintException: [0]: Memcache \OC\Memcache\APCu not available for local cache (Is the matching PHP module installed and enabled?)

Nextcloud version 22.2.0

Please give me a hint.

**It seems the problem solved: [OCC won't run with memcache/apcu - #8 by feligato](https://help.nextcloud.com/t/occ-wont-run-with-memcache-apcu/119724/8)**
