How to forward a subdomain to a post

Hi,

I would like to forward

southcyle.360philippines.com

to

https://www.360philippines.com/businesses/south-cycle-bike-shop

I’m hosting in godaddy. When I add a subdomain there is a field for “folder” I enter /businesses/south-cycle-bike-shop . but this doesnt redirect to the page i want to.

when I access https://southcycle.360philippines.com/ it says

Forbidden
You don’t have permission to access / on this server.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

Has anyone tried this?

Thanks,
Milo
