I would like to inquire about an issue with Nginx server. I have configured multilingual URLs in the background, where accessing www.domain.com automatically redirects to www.domain.com/de, but it shows a '404 NOT FOUND' error. How can I solve this? When I raised a support ticket, the administrator replied that they only handle .htaccess files, and they do not configure Nginx. Could any kind-hearted technical experts please help me? Thank you.
