Permalinks don’t work after switching from Apache to NGINX

@threadi I’m sure. As I wrote, NGINX works properly, I tested it on a clean WP instance and I’m using the community recommended configuration.

@gappiah Sure, here is the entire configuration block for my site. I anonymized the site. It wouldn’t make sense that it would be fine for all instances and not for a single instance if it is the same.

No, my server only runs nginx, including X dozens of WP instances and custom applications. Please stick to what I wrote in the original post.

Of course we tried reloading nginx. As I stated, all WP instances running on my server are working without this problem. The problem only occurred with this site because there was a migration from a hosted solution with apache. 🙁
