fresh install with RPi-Buster img.
Installed Pihole, No-IP and Nextcloud (in that order).
everything is working except logout of Nextcloud.
on logout nc shows a error page wit “access denied” and “CSRF check failed”.
Url in browser shows
as far as i understood the problem lighttpd changes “+” symbols into spaces in the token so nextcloud thinks the url was manipulated and doesnt accept it.
