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
