I'm trying to make a * cert off my hosted services with the Community Edition of LetsEncrypt. I'm using the manual DNS update method. Every time I try, it changes the DNS _acme-challenge value on me. I'll go into my DNS manager, update my TXT, follow the instructions (Once completed, select 'Request Certificate' to resume.) It fails again, another message with a DIFFERENT txt.
Basically, every time I try, the TXT requirement changes...but I don't know where to find what it WILL want until it already changes it.
