@julian Just works as intended.
The approach here totally works.
As you kindly suggested, it's my mistake not to have set subdomain by DNS.
I somehow misunderstood Ngynx takes care of subdomainsDNS IP routing, my bad.
Thanks a lot.
@byAppeL look in your browser address bar. Are you accessing the site at http://foro.az-rp.com:4567? My guess is that the port (:4567) does not show up in your address bar, and you're accessing the site at one of the default ports. In that case, remove the :4567 from the url value in config.json.
I don't know how many times I'll have to say this, but the url value in config.json should be set to exactly the url at which you access your site. The protocol, domain, path, and port should all be identical to what you see in the address bar of your browser.
