Hi @kaggixx
see your check, ~~2 hours old - https://check-your-website.server-daten.de/?q=xn--hvc-ula.se#url-checks
You have a redirect
https://xn--hvc-ula.se/ -> Location: https://xn--hvc-ula.se/
so it's a direct loop / redirect https + non-www -> https + non-www.
The www version doesn't have that loop, creating a screenshot with the www version works.
Your shared 443 definition doesn't have such a redirect -> so that block isn't used. Or it's a redirect from your application, .htaccess or something else.
