Argo tunnel returns 1033

I spent a very long time getting argo tunnels to work for me and finally it did, somewhat. My domain finally realises it is part of the argo tunnel but I get a 1033 error.

so i stopped the tunnel and tried again and now it broke

now it works but i need to visit www.domain instead of domain

oh it’s because of cname flattening

but I want my root domain to use the tunnel

First make sure your application is responding to root domain then configure the Argo tunnel for root domain and done
