Good morning,
Yes, the redis service is active on startup and running.
According to the documentation, I only made two changes to the /etc/redis/redis.conf file

My file is configured like this:

I will now check your suggestions about /var/www/html/nextcloud/data/nextcloud.log
It is
sudo -u www-data php -f /var/www/html/nextcloud/occ log:tail -f
I’ll be right back with the return.
