I am currently on Odoo 16 Online Enterprise edition

My Domain Registrar: Hostinger

Nameservers maintained of Hostinger 

Changed CNAME records and pointed www to odoo database url as documented

Now only www\.reliablemotortrainingschool\.com

is\ getting\ redirected\ to\ my\ odoo\ database\ website\ app

But\ naked\ domain\ reliablemotortrainingschool.com is not getting redirected to my odoo database website app

Can someone please guide how to make this work as this seems to be general issue which might be faced by main new subscribers of Odoo but there is not detailed documentation in Odoo 16 Online 

Some things I tried to solve but didn't work:

1. Redirect/Forward url - temporary 302 or permanent 301 in Hostinger : this didn't worked as Hostinger DNS is not allowing to redirect to own domain. And if I enter odoo databse url - my URL bar changes to odoodatabase for all users which I don't want. 

2. Saw someone informed to use Cloudflare or NGINX to redirect. So tried to change nameservers to Cloudflare to use their Nameservers and added forwarding URL in page rule along with maintaining A records in DNS. But this is not working or I may have not configured Cloudflare properly.
