[44net] LetsEncrypt SSL certificates for HTTPS within the 44net

Hi Folks, I'm having some trouble trying to get LetsEncrypt SSL certificates authorised for use on my WWW devices. The issue seems to be that I do not have control of the TLD and so I can never authorise the issuing of the certificate. I've tried *.ni2o.ampr.org (generic catch all), fqdn.ni2o.ampr.org (device specific) and many other variations but they all fail at the authorizing of the cert. What am I doing wrong? I'm using LetEncrypt (free not-for-profit) SSL certificates successfully in other areas but i do control the domain for those. Thanks for your help Mark / G7LTT
