Plesk Obsidian returns the following error when initialized via CLI with
plesk bin init_conf --init:
CONFIG_TEXT: No file(s) found for glob /var/log/modsec_audit.log
CONFIG_TEXT: No file(s) found for glob /var/www/vhosts/system/*/logs/accesslog
Plesk Obsidian activates Fail2ban and Modsecurity by default.
Fail2ban tries to be activated before ModSecurity.
Since no domain exist on the server
/var/www/vhosts/system/*/logs/accesslog cannot be found.
This has been reported as bug ID PPPM-11103 which will be fixed in future updates.
Currently there is no workaround.
