Как обслуживать Autodiscover.xml с помощью Nginx

Я пытаюсь обслужить файл Autodiscover.xml с помощью Nginx:

Ниже мой конфиг:

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;
        }
}

Проблема в том, что он не может обслуживать файл Autodiscover.xml при запросе с прописной буквой A

Если бы кто-нибудь мог помочь, было бы здорово.

Когда запрашивается Autodiscover.xml, он должен повторно отправить его на autodiscover.php, который вернет .autodisocver.xml. Это делается для того, чтобы обслуживать разные домены.

Файл находится по адресу /autodiscover/autodiscover.php.
