I saw the following link:
If i have the following senario would this still work:
I have a local Server connected to internet connection having a static ip.
I have a domain in cloud (domain.co.za)
I have other A records like pop.domain.co.za . . . , but also one portal.domain.co.za referencing my local static ip.
I can access my ERPNext server using portal.domain.co.za, but would like to know would it be possible to install Lets Encrypt on such a setup?
I see Prequisites:
1. You need to have a DNS Multitenant Setup - (This OK) 2. Your site should be accessible via a valid domain - (NOT Sure) 3. You need root permissions on your server - (This OK)
