solved the issue for me, thanks.
- sudo -u www-data php occ maintenance:mode --on
(in Nextcloud folder) - sudo redis-cli -s /var/run/redis/redis.sock
- flushall (OK was response)
- exit
- sudo -u www-data php occ maintenance:mode --off
(in Nextcloud folder) - sudo -u www-data php occ files:scan --all
(in Nextcloud folder)
But there was no password in redis? Is this right?
