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
any tips what the problem could be?
it seems to be a NextCloud issue. So might be better to report if over there. I just googled for the error message and already found some entries.
After 4 hours of searching the web i found a solution.
it seems lighttpd is the problem.
ind the lighttpd.conf the line
"url-normalize-required" => "enable",# recommended
needs to be chanced to
#"url-normalize-required" => "enable",# recommended
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.
After correction in lighttpd.conf, you have to restart lighttpd:
