Description of my issue

Hello, I recently upgraded my yunohost instance and now suddenly fail2ban fails to start… I think it’s something to do with nextcloud but I am not really sure… for context, I have moved my yunohost.app folder to an external volume (and sym linked it). I am confused because I think the symlink shouldn’t have easily been destroyed right? so how did this happen? how can I fix this problem?

Here’s the yunohost paste of the error log

I think I figured it out…

I still don’t understand how the symbolic link got removed

Hello,
@buoyantair
check the configuration in /etc/fail2ban/jail.d/nextcloud.conf
The line logpath = /home/yunohost.app/nextcloud/data/nextcloud.log must point to the nextcloud log file. If this file does not exist, fail2ban cannot start.
