I've been following a blog on how to install ASP.NET Core In .NET 5 App On Ubuntu 20.04. When I visit the link api.example.com, it showing default apache page. It should be showing me the ASP.NET Core app.

All the application files are stored in /var/www/api/ and ownership has been given to www-data

VirtualHost api.conf

In the VirtualHost I have the following configurations and the conf is enabled.

<VirtualHost *:*>
    RequestHeader set "X-Forwarded-Proto" expr=%{REQUEST_SCHEME}
</VirtualHost>

<VirtualHost api.example.com:80>
    ProxyPreserveHost On
    ProxyPass / http://127.0.0.1:5000/
    ProxyPassReverse / http://127.0.0.1:5000/
    ServerName api.example.com
    ServerAlias api.example.com
    ErrorLog ${APACHE_LOG_DIR}api-error.log
    CustomLog ${APACHE_LOG_DIR}api-access.log common
</VirtualHost>

Add Service

The following service configuration has been added and service has been enabled.

[Unit]
Description=Api

WorkingDirectory=/var/www/api/
ExecStart=/usr/bin/dotnet /var/www/api/Api.dll

KillSignal=SIGINT
SyslogIdentifier=api
User=www-data
Environment=ASPNETCORE_ENVIRONMENT=Production

[Install]
WantedBy=multi-user.target

When I run sudo systemctl status api.service I get the following
