Has anyone ever done this using a UC version of the certificate where you put all the names you want to bind to a single IP address and have it work with letsencrypt.org.   I have done it in the past with other vendors but not sure if this works with letsencrypt.org ?

I created a base cert and then exported it with adding a password.  I tried to use it an it say invalid cert.  I will try again but I would love to use this as I use this with all the web domains hosted. 

Thanks
