Just scroll down to the end of the initial post (below updates). I use the zerossl site to generate the letsencryptit certs. All free, works well. Hopefully the how-to is good. I stopped using it this past summer, but it was current then (I actually read the how-to each time I had to renew because I could never remember how to do it). Let me know if I need to fix anything. My long-term goal is to put that and some other how-to’s onto Github and then link to them within BI Fusion so you can find them easier.
