So I built a lamp server to test letsencryt, dehydrated solutions your presented. For me, they all failed. I have been doing IT for 40 years and I thought I followed your instructions fairly closely. But I do have bad days. 

I have a couple of wordpress servers with 10 websites on each, so I need to see a solution that works here. Just for info these are blogs and info sites for the most part and are not critical. All my customer websites are elsewhere.

Here is my whole confconsole log since install

I am moving to setup another server for testing purpose using wordpress since Lamp appears to use Nginx.

As I said no worries and I will watch your efforts.
