I have suddenly been unable to activate my Nextcloud jail due to a permission denial. I noticed this when the server sent me the error log. I have specified logfile=/MY-NEXTCLOUD/data/nextcloud.log as the jail.
User was banned 4 days ago after multiple false logins. I trusted the user’s IP and allowed him to use the site. For the next 3 days I was able to use fail2ban and Nextcloud Jail without any problems.
I disabled selinux and it seems that the Nextcloud jail is not rejected. So why is NC jails suddenly being rejected today? I have it set up as this manual indicates.
Nextcloud 24.0.6, CentOS 7.9, PHP 8.1.11, Nginx 1.20.1
