Ok, fail2ban is installed and running. That was a good idea! The mysql table is cleared and also the browser cache.
Same behavior.
I think the problem is still a permission as you can see in the log: “Permission denied (13) at /var/www/owncloud/lib/private/Session/Internal.php#206”,”
What is the correct permission setting to “var/www/owncloud/lib/private…”?
