hello, i am using the newest ispconfig-panel with nginx on an debian13 VPS. I want to block countrys with geoip, like if ($blocked_country) { return 403; } that works fine if custom error sites not enabled. But when enabled i got error 500 instead of 403. I have fastcgi_intercept_errors on; in nginx.conf and tried various syntax like error_page 403 /error/403.html; in the nginx-options within ispconfig, but nothing will work for me. Does anyone have a tip on how I should proceed ? Thanks
