    I'm having a very strange problem migrating a site into a fresh centminmod server (built yesterday). I'm getting a 400 error across multiple browsers and computers when trying to access index.php, but admin.php seems to work just fine.

    I've checked and triple checked all the obvious things that I can think of:
    * Added autoprotect-bypass files
    * Permissions
    * NGINX conf settings
    * Xenforo file check
    * Nothing in any error logs
    * Downgraded NGINX
    * Downgraded PHP

    Exact error is as follows:
    Code:
    Error 400
    We're sorry, but we could not fulfill your request for /index.php on this server.
    
    An invalid request was received. If you are using a proxy server, bypass the proxy server or contact your proxy server administrator. This may also be caused by a bug in the Opera web browser.
    What am I missing here?

    Nginx 1.19.x
    MariaDB 5.5/10.x
    A bug or feature in that addon causing issues ?

    Almost certainly a bug. Otherwise, a browser 400 error is a terrible feature.
