Nginx – How to serve Autodiscover.xml using Nginx

I am trying to serve an Autodiscover.xml file using Nginx:

Below is my config:

upstream autodiscoverexamplecoukbackend {
        server unix:/var/run/php-fcgi-autodiscoverexamplecouk.sock;
}

server {
        listen 80;
        listen 443 ssl;

        ssl_certificate /etc/letsencrypt/live/autodiscover.example.co.uk/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/autodiscover.example.co.uk/privkey.pem;

        server_name autodiscover.example.co.uk;
        root  /var/www/vhosts/autodiscover.example.co.uk/htdocs;

        index index.html;

        error_log /var/www/vhosts/autodiscover.example.co.uk/error.log;
        access_log /var/www/vhosts/autodiscover.example.co.uk/access.log combined;

        #location ^~ /autodiscover/ {
                #index autodiscover.php;
                #rewrite ^/.*$ /autodiscover.php last;
        #}

        location ~* /autodiscover/ {
                rewrite ^/autodiscover/autodiscover\.xml$ /autodiscover/autodiscover.php last;
        }

        location = /robots.txt {
                allow all;
                log_not_found off;
                access_log off;
        }

        location ~ \.php$ {
                try_files $uri =404;
                include /etc/nginx/fastcgi_params;
                fastcgi_pass autodiscoverexamplecoukbackend;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                fastcgi_param PATH_INFO $fastcgi_script_name;
                fastcgi_intercept_errors on;
        }
}

Problem is that it isn't able to serve the Autodiscover.xml file when requested with the uppercase A

If anybody can assist that would be great.

When Autodiscover.xml is requested it should reweite it to autodiscover.php which will serve .autodisocver.xml back. It does this so it can serve different domains.

The file is located at /autodiscover/autodiscover.php
