Can't acccess Apache using ServerName

I'm running a local Apache server with no access outside my network. I want to be able to navigate to sites by the server name.

For example, where hostname is my server's hostname and home.lan is my local domain,

• I CAN access Nextcloud using the alias via https://hostname.home.lan/nextcloud
• I CANNOT access Nextcloud using the server name via https://nextcloud.hostname.home.lan

What's wrong with my virtual host setup below?

<IfModule mod_alias.c>    Alias /nextcloud /usr/share/webapps/nextcloud/</IfModule>...<VirtualHost *:443>    DocumentRoot /usr/share/webapps/nextcloud    ServerName nextcloud.hostname.home.lan    ...</VirtualHost>
