Website in second bench not visible

Hi there
I have an issue and can’t find anything related.
I have the original frappe-bench with multi tenancy on and 3 websites, all three visible on browser by DNS.

I’ve bild a second bench, in the same frappe folder.
In this second bench I have installed frappe and erpnext in apps folder. created a website in this second bench, add it in hosts file, but this time i get a 404 Site not exists, when trying to access this website in browser.
All other 3 sites from the first bench are accessible by DNS, but this from the second bench, no.

Does anyone know why, pls?

Thank you
