Comment Comment by bruce511 Came here to say the same. I use DNS-Challenge rather than HTTP-challenge, and that makes internal servers trivial.You need a DNS provider which supports API calls (I use DNSimple) but the core is all very straightforward.To prevent having to include DNSimple authentication on the client's internal server I have a small API server on the web which does the Acme work. parent bruce511 3 months ago
