Both sites refusing to connect after setting up multitenancy

So I created a new site and set up multitenacy using this guide: https://github.com/frappe/bench/wiki/Multitenant-Setup

I also emptied the currentsite.txt file

and also used this command bench config dns_multitenant on

as suggested here: https://erpnextdeveloper.blogspot.com/2018/08/dns-based-multitenancy.html

Now both sites are saying, ERR_CONNECTION_REFUSED

What could be the issue here? Bear in mind this is on ERPNext 10
