I have a subdomain: webmail.domain.it who points to a folder of my website (domain.it/webmail)
My website work with a SSL certificate, on www and without www (www.domain.it and domain.it)
My subdomain have a different SSL certificate (let's encrypt) and work only if I write webmail.domain.it, and give me ERR_NAME_NOT_RESOLVED if I write www.webmail.domain.it
On the subdomain hosting settings, there is a redirect on https protocol, and on IIS settings, there are not "require ssl" flag selected, if I try to select "include a subdomain www etc" on let's encrypt, it try but give me errors for cannot reach the domain, for the same errors.
