Just typing

ncp-report

in terminal, should output most important info, including logs.

NC log file is usually found at /var/www/nextcloud/data/nextcloud.log
NCP log is found /var/log/ncp.log
Most standard logs (Apache,Mysql,Redis,Fail2ban) are found under /var/log/

You can use pastbin.com for long log files, just link to them here.
