subdomain.xyzsecurity.xyz sent an invalid response.
I am trying to use one of infinityfree free SSL certificates. I managed to make it work for the main domain (xyzsecurity.xyz) but did not manage to do it for my subdomain (my subdomain is called subdomain.xyzsecurity.xyz). I tried two different type of SSL certificates but still no success. I am attaching the cname screenshot for your reference. Any help is highly appreciated
